If you haven't already, I recommend asking the same question on the mod page. There will likely be more people there who are familiar with your issue.
I don't work for EA.
You did installed the mod after the DLCs?
Did you edited the "BIOEngine.ini"?
Do you run other mods besides MEUITM?
I'm a little late to this topic, and I'm not sure quite what you mean.
I have MEUITM installed and working just fine with both BDtS and Pinnacle Station. (Those are the only DLC for ME1, and Pinnacle Station isn't worth the time anyway.)
So maybe some more details about what's going on would help?
As @Holger1405 asked, in what order did you install things?
Have you installed any other mods?
At what point does it crash?
And please provide a DXDiag report.
