YesDid you try to subscribe to mods at the steam workshop?
No. Didn't know it was possible.And did you try to install a mod without WSE?
OK, I get this, but why can't I play the game from the TW downloadable, without any mod? Isn't steam serial compatible with the game downloaded from TW?The TW developers have in general not the obligation to guarantee that every mod works, especially the ones which requires WSE (which caused most probably the "incorrect serial key" issue). That's an external tool developed by modders. If you can play the Native game via steam, it's working fine. The rest is not a real technical problem of TW.
