I just tried a fresh install and that loaded fine, but yeah it just simply doesnt even load in my current collection, something has gone wrong with the update and its stoping at least 3 users in the forum from using LB.
Not sure what it is though as it doesnt even crash or load at all. Even just copied the exe files from the an installation from the other directory and it doesnt work. I do have a very very big collection though, 180k games. So Im guessing its something to do with the databases and XML files.
