Go to %AppData% (C:\Users\(GamePlay2909)\AppData\Roaming), back to AppData, then to Local, and then just hack away at the AEWVS save files until the game works. (C:\Users\(GamePlay2909)\AppData\Local\AEWVS)
If it still doesn't work, try downloading it again or go and download another version. Versions earlier than 0.16 use "STROBOVSKY" folders instead of "AEWVS" folders.
