I tried the default UI and ít worked again... then installed the new profit update again (without autoupdater) and i got crash again? Is there a major bug in that release?
If it was a general problem I'd have people freaking out all over, but since nobody complains you can conclude the UI works fine, so something must be wrong on your end. Did you really delete your entire UI\ProfitUI folder and had the updater redownload it all?
