Ben - thanks for the info.
A few things:
When logging into support at ni.com to submit my message (which started this thread) I was not under the impression that it would become a forum topic. I thought it was going to a NI engineer - it's NI support, right? I feel a bit ashamed it became a community topic. That was not the intent.
Also, Charlie and Altenbach: thank you for your support. I was able to continue my work at home, albeit temporarily.
Finally, realizing a program cannot usually open a newer version file didn't come to me at the time of my original post.
However, assuming that LabVIEW is C based, I don't see any real reason as to why 7.0 cannot open 7.1. Sure, I'll go to the seminar (I'm on the wait list) and hope for version 7.1.1 to open the 7.1 vi's created in the lab; this is just another testament that real engineering costs money.
Regards - Micah.
