I buy 2 DLC on greenmangaming Ultimate Vault Hunters Upgrade Pack and Ultimate Vault Hunters Upgrade Pack 2 after install both editor and trainer 22.214.171.1241067 08.29.2013 start crash game after while I'm in Captain Scarlet DLC now. I wait until new ed/trainer and try it today yet it still no change
Today I received email from support.2k on my question "Is there any way to uninstall / block specific DLC?" (I have problems with trainer for B2 after buying Ultimate Vault Hunter 1 and 2 DLC) answer: There is no way to do that. So, no help here no chance to dodge unwanted content on steam. Looks like only choice is buy another copy Borderlands 2 for other steam account. It's not really inspiring for buying any further DLC.
I'm really missing 90's when people rip off game industry, not game industry people like today
