redownloaded this freaking game and still getting this freaking bug. Free Knights this freaking bs.
Navigate to your Aeriagames folder.
Right click the AVA folder and select properties
Uncheck read-only and apply changes, select apply to subfolders, hit ok.
My computer likes to randomly set files to readonly so I have to do this every now and then. It fixed my XIGN having 3rd party error and I DC less frequently.
