Every time I open up Blockland, this appears! "OK" Makes blockland quit! I Iz on a mac. WHAT DO I DO?
If it happens each time, then the files is not copied. I'll add a thing so it will check if the files are copied, and if they are not, announce that they are not, and you sir are screwed.
Im having this problem too... :C I tried redownloading, but it did nothing. Help... Yes, on a Mac.
EDIT: I also deleted the system, but that made it worse. I cant even start Blockland now.
The best way to get support is by provide a console log. Even though, seems that it fixed by itself.
