By your description it sounds like you've taken the right steps to make things work right. Do I understand you have a small test application that reproduces this JIT problem? Would it be possible for you to send it to us so (place the entire project folder into a .zip file first) we can see the problem first hand ourselves? Once we do that we'll be able to determine where/how it is going wrong. You'll need to open a new support ticket before you can attach a file to send to us.
