I downloaded this pack and it was awsome, and i found a solution for the problem which, deletes all class files. So, if you run compile, you'll get a error, there are few files which give errors, so scroll up the compile windows, check the script name and delete it from the scipt folder, run compile again, and all scripts are back. Worked for me : ) I have no idea how to make does scripts work which give errors but you can now use other scripts normally : )
