Same problem here too, i thought i was the only one.

I only have this problem with my Sidewinder, mamba max witch the program works fine (both of them) and my MMM is also working like it should.

I tried 2 Castle link cables to see if that was my problem but it dosn't matter at all, they both work.

Once i plug in my sidewinder the castle link program shuts of and gives me an error window saying it encouterend a serious error.

Please CC help us ;)
