When I click the .exe it doesn't run, and when I click the .jar I get "Sorry, fatal error - please let Majalis know! Error: Error writing file: data\profile.json (Local)" I have applied full permissions to the whole folder and sub directories.
Does it create a data folder? Try creating a data folder - it's strange that it doesn't have the ability to write. I assume it also doesn't create an error.txt file with the full error.
