I guess I have to reinstall...is there an easy way?

I think that all you need to do is right-click on CoD, select properties and then find the button that says "delete local content".

However, first of all go into the documents\1c softclub folder, backup your conf.ini, confUser.ini and confs.ini, in case you don't want to redo your controls and overlay windows from scratch, then delete this entire folder too.

Finally, right click on the CoD icon again in Steam and select install/download or however it's labeled, it will download everything from scratch and re-install.
