Oh no the dreaded bedug error ? Hmm you've cleared the registry and you've restarted the computer since? Did you add or hex any toyz recently? That's when I get this message the most!
As always my fall back is a complete reinstall, at this point in our long history with the game as we keep pushing it to run on newer operating systems a reinstall is the only thing I found that beats the debug error now :/
I haven't done any hexing recently, and i hadn't thought about it being a baby file! I took Reghan's file out and swapped with another kid to see if that works. If not i'll just reinstall :/ I don't normally have problems with my game, so i was definitely a little surprised to see this pop up and then not go away, haha.
EDIT: No luck. I'm gonna try with all my kids out and if that works, add back in until i find the problem child (no pun intended hahaha), and then if that doesn't work, full reinstall it is! >.<
