You have NOT deleted all patch files: you can clearly see that the first call, and many more below that, refers to a file named "scr_patch.rpy". Check again and make sure that ALL patch files (can be .rpa, .rpyc and .rpy) are removed. If you STILL have the same issue, the only thing you can do is a clean install: make sure you save away from choices and modded/patched sections, delete the ROOT folder (basically: delete everything), and reinstall from the base .rar archive (un-modded, un-patched). Then check again if the same error occurs. Finally, if even THAT doesn't fix it, last thing i can suggest is starting a new game with the original game, again un-patched and un-modded
