Hi
You seem to be tying yourself in knots this is also coming across in your description of whats actually wrong.

1) break the problem down into bite sized chunks
i) use basic geo to show the issue, not 10 gig sim files
ii) where does it go wrong

2) Post a scene file with the problem. Explain what you want to do in a short concise sentence.

3) Don't panic and keep cool ! .

4) PM with your email address, Im feeling generous !
