[Vehicle class VirtualMan_EPOCH no longer exists]

I get the error "mpmissions\__cur_mp.Altis\mission.sqm/Mission/Entities/Item3/Entities/Item0.type: Vehicle class VirtualMan_EPOCH no longer exists" when trying to join my private server this is a new problem and was wondering if this was an update issue or what, it comes up repeatedly and the screen flashes after clicking join

["Include file x\addons\a3_epoch_code\System\init.sqf not found"]

Now I Did all this i think properly and for some reason that youtube video is private and i cant watch it and also the two errors im recieving I see them in the files one I can only see through the PBO manager and just in files but dont know why they cant be found do I need to change the itit.sqf and dummy file with text editor or something like that

["Include file x\addons\a3_epoch_code\System\init.sqf not found"]

I receive the error "Include file x\addons\a3_epoch_code\System\init.sqf not found" after Arma 3 crashes while trying to join my own lan server. I have see on server tutorial videos that this is a common issue but not on the forums, I've seen people say that something is outdated but I Downloaded the latest server from the official epoch website version 1.58 and the epoch mod from armaholic I also have the steam version but don't know how to create the server with using the steam version as it puts the epoch content in the workshop folder in steam. I also have the error that comes up when putting in my server password which is "Script epoch_code\system\dummy.sqf not found" somebody said on a forum that its case sensitive so you have to change the file name to that of the error message so in my files it would read "epoch_code\System\dummy.sqf" and I would have to change the S in System to a lowercase and it should work and I did this but unfortunately didn't test to see if that solved the issue before solving the next issue which was the crash and the error message "Include file x\addons\a3_epoch_code\System\init.sqf not found". I tried all sorts of things and messed quite a bit up in the process Some files were different from the steam version and the manual armaholic version so I replaced the manual instal the @Epoch folder with the contents of the steam workshop install and just ended up having to redownload 10 gigs of arma 3 (I probs accidently mixed epoch addons with Arma 3 addons, i have been at this for quite some time and have been trying everything I can thinks of im even trying things that i think of while typing this post) the video i followed was https://www.youtube.com/watch?v=EYuhF2u1Ecs I have read all the comments of the video and came accross the possible fix of the links he gave for the server files are outdated I downloaded the new ones from the epoch website I have unzipped the zip file using winwar and put the contents of the file "server_install_pack" in my arma 3 folder and to my knowledge everything looks like it went to the right places the mpmissions were put in the folder. Im also using a server tool TADST v3. The things that I believe could be going wrong are PBO files which I have manager and cpbo. in video i see the icon being a red booklet with PBO on it but my icons for PBO files are of internet explorer I read something about double clicking on it but it doesn't do anything when I click on open in the internet explorer thing for PBO files. If you need anymore information ask but I live in japan so response times may be akward my placement in japan is also a huge part on why im setting up my own server since my lowest ping to a server has been 330 or so but most are around 600 ping.
