Not sure what you said but I got 1.2 to work by moving my all the 3 files to the IB2 folder so I'll install the 1.201 patch now.
Btw this is the only availability IB2 mod using the Med2 engine right and is there a way to know if the 1.2.01 patch installed correctly because I don't see a difference? (like what's an 'au naturel'.)
