I tried all of these suggestions (except 1):
1) I reinstalled the 476 build. (complete uninistall, reboots after uninstall and install)
2) I sent the log file to Matt
3) I did not try MJ, since I uninstalled it
4) even though I uninstalled MC, all of my settings seemed to be preserved. (i did the uninistall as a different user)
There is plenty that is unusual about this PC. However, it all used to work. (I tried MC for a while, uninstalled it, then tried MJ, and uninstalled it when I decided I was going to pay for MC).
Some things that might be relevant (but they used to work):
- I installed things as administrator, but am using my user account.
- My user profile gets saved/loaded by a very unusual custom login scheme set up in my department
- I have tried putting the library in my profile, but also in a "normal" place on the local disk.
Everything else works, except for playback.
I'm stumped. I guess I don't NEED such a sophisticated media player in my office...
