Hm, there aren't too many other known fixes to the Alpaca Box, as it is a known issue and it is being worked on.
The only other things I could suggest doing would be trying this
(though make sure you make a second copy of the file before removing it completely unless you want to try to reinstall again, as many people had issues with errors with this method) or you could try running the game in Compatibility Mode ( Windows 7
and Windows 8
, no changes if you're running XP).
If neither of those work, I'm not sure what else to tell you. As long as your computer meets System Requirements
then the only other thing I could suggest would be reporting it in a Game Support ticket
. Aeria may have more suggestions to provide, just make sure you let them know what you have tried.
Thanks for your patience, hopefully the Alpaca box issue can be resolved soon.
