(FIXED) different checksum yet no mods runnin

Hello Sins Players ,

Im having a little problem and im wondering if any one else as the same issue.

When i join a online game just before i enter i get some thing like this "cannot join because i have a different mod checksum" however im not runing any mods. I though maybe i had mess up some of the original files when i did my mods but i reinstaled and nothing change. Also i ask some of the other players if they were running a mod but no they were not.

I am using the latest entrenchement 1.41 and vanila file 1.18 fixed patch files.

Help and suggestions are very much appreciated 

Thx in advance
