You gotta be crapping me... sigh alright I got it working now. I have no idea why it didn't work before.... but it works now.
I'm using windows 10 so this should be relevent to a few peeps having problems
Go to settings, Click update security, on the left panel click Windows Security, Click open windows security, Select Virus and threat protection, under virus and threat protection settings select Manage settings, Scroll down to exclusions and select add and remove exclusions, click Add an exclusion, select folder, find your dyndolod folder and select folder.
you may need to do the same for Mod Organiser 2.
I had already done this btw, Mod Organiser 2, Dyndolod and Texgen were all selected as files and that seemed to work in the past, I guess we just gotta select it as folders now.
