Do you can send me your exe file, you use, so that I can test the problems?
I tried one more time, this time with filename "CreatureIsle.exe" and now it worked :/ It may be a good idea to add a way to choose an .exe file for modifications. Otherwise, great job!
By the way, archive is still broken, could you upload it somewhere else and give a link? Currently I can't make my own archive and upload it myself to my ftp server.
I added two mirrors!^
Now downloading is not longer a problem^^
