T6/T5 error message while loading into BO1/BO2

[BTX_Beatz]

I can no longer launch T6/T5 from the Plutonium launcher. I was able to load into the multiplayer menu for T6/T5 before it started continuously crashing upon launching. Could it be because I don't have any user maps in my T6/T5 files?
I can't find the user map files as well for download. If I need a user map file, can I get some assistance?

My IW5 Multiplayer works perfectly fine and runs. I do have user maps downloaded. IW5 Multiplayer works perfectly fine and runs.

Thanks!!
