ERROR: String not found?

[DeletedUser]

Only thing I can guess is that it may be a similar problem like I once had in Half-Life. Half-Life uses a text file for the mod you're using and it pulls text out of it. The string would be the text. Like they define a certain piece of text to output the string.

So you may be missing a file that it needs. If you have a 5.0 playable, I don't know what to say. My only say would be try to patch, but if you patch you're screwed of 5.0.

This is 100% a guess, so sorry if this is 100% wrong.
