Can't buy or sell anything in traders

[TheButterManV1]

I have repaired uninstalled and reinstalled Arma 2 , Arma 2 OA , DayZ , DayZ Epoch and for some reason I just can't buy or sell anything in the trader's and my trader screen in a bit small compared to the pictures I have seen of it on Google.I can view everything in the shop and scroll down but just can't buy anything.I have looked around and anytime I bring it up on Google all I get is people having problems with trader's on there server anyone have an idea's on what to do?

This may be a specific problem with a server.

Make sure that traders work on a server that is maintained regularly by the owner.

No I have played on more then a dozen Epoch server's if not more.(sorry I didn't mention that it's pretty late where I live)

Uninstall Arma through the usual method, via steam or add-remove program in your systems settings.  Then, delete the arma folders (they'll still be there and possibly even have stuff in them), then, download  a cool registry cleaner called CCLEANER from CCLEANER.com and run the registry cleaner in that .. Run it several times until it finds no more issues, after each cleanup it will find new issues which the last clean up created (don't ask, it's complicated, just do it and I promise it works).

 

After that, then reinstall Arma and the Epoch mod :D
