well, givent hat we don't know exactly what edits you made -- but you only have 2 mods -- I'd suggest that you upload a clean set of files.

Okay, I see where the OP stated he manually did edits, not sure if they are both one mod or 2, but where is it stated how many mods the OP has installed? Just because the OP stated the manual edit, does not mean that's all the mods installed.

But you're right, it's not definitive and there could be more.
