Here is an easy way of deleting the ava gameguard error which some people may have!
In this error ava will ask you to send them the erl files from the gameguard folder! reason: the erl files should be deleted after every session if there are multiple erl files into the game folder it will give you an error which makes u unable to play ava. In stead of sending ava these files and wait for a few hours for the problem to get fixed...
You can easily just go to your ava folder, click on binaries then click on the gameguard folder.
And delete THE ERL FILES, don't delete any other files! (You can also drag the erl files into a map, in case you still want to send them or in case you would accidentally select a file you don't have to delete.)
It worked for me... Hope it works for everyone who has this error
