Glad I could help.
Such simple solutions... the place I used Inventor at restricted internet access to all computers except the boss, the sales guys, and one public computer. Well everyone always STARED at the public computer that was always up front when someone was on it, like they were evoking the light at the end of the tunnel or something.. (What's so important that HE needs to use the internet computer?) that no one usually used it unless there was no alternative.
I tried expressing that peer support for technical issues can often save HOURS and HOURS of trouble in a single SESSION, but they just replied "Well you should be able to just do your job. If you aren't trained to handle these problems then maybe we should find someone else" ...they also wouldn't shell out cash for training... it was a real "sink or swim" situation... and no one knew how to swim anyways.
I vividly recall that a couple of the designers spent vast amounts of time trying to troubleshoot that very error popup to find out if it were a symptom of a larger problem, what they can do to solve it, prevent it, etc... and to no avail.
Funny how it was solved in a single second (I got it to open files without the popup now by a series of resaving and updating in the proper order) on a single "oh btw" comment, that wasn't even the aim of my post...
I'm so glad my employers recognize the benefits of good support groups.
