I didn't know that as I am not the admin (we are compartmentalized). I asked the site's admin and she indeed said the folder was set to run with 1.1 and is doing the change now as we speak.

Would be nice if MS gave us an error message that somewhat referrered to the real error. Something like: "Compiler version doesn't match".
