If anybody out there sees this and doesn't mind helping I really need help with the mates on my assembly. I have been having this problem for days. An assembly with 3 subassemblies that previously worked, no longer works when I turn one of the subassemblies flexible(subassembly3). I've tryed many things but I just can't seem to make it work and now I'm running out of time.

Please I really need help!

To anyone who is willing to help me, please warn me that you will first in the dicussion. I will leave a copy of the assembly here.
