I am starting to come to the realization that we perhaps somehow used too few sub assemblies. We've done exactly what we've done in years past, however I guess with the increased complexity of Inventor 2011, we had to re-adjust how we put our assemblies together. Adjusting the Level of Detail did nothing, and previous years assemblies open just fine.

It must be some combination of incorrect/conflicting constraints and the sheer number of them. I just didn't think that even with that it could bring hardware like mine to its knees.

I'll have to keep a closer eye on this kind of issue next year, so hopefully we can catch it before it ever even becomes an issue.

Thank you to everyone who assisted me.
