Am I the only one having issues with the Cient Extension? Every time I try to load a save game the CE stops working and shows the error "failed to load walkmesh" or something similar.

I'm having the exact same problem. Still trying to find a workaround but no luck here. Either the client extension needs to be updated or there must be a quicker solution buried somewhere but i haven't found it yet.

Just bumping this topic, as I'm having the same problem. I was able to get through the entire OC and well into MoTB before my save game suddenly stopped loading. Trying to load a fresh save in the OC causes the same problem. I'd love to at least finish MoTB, but if no one can give me a fix for this, I'm up a proverbial creek.
