For the record, you can mod on BLUS/BLES/NPUB/NPEB it just depends on the mods developed at that time and how much they are supported. Yes, BLES is more researched and modded due to the French. As for this loading issue, perhaps reinstall the game I guess if reinstalling updates in order did not help. One thing I can think of that might be the issue, is you could have a BLES game but might have installed BLUS updates? This might just cause this issue your having!
