You're not alone Brac. I've a very similar computer configuration and have the same problem. I can sit here and watch slplugin.exe quit before my eyes. Really wishing it would log WHY it's exiting.
I've done the driver dance, the Adobe Flash Reinstall dance, the Java Reinstall dance, the Quicktime Reinstall Dance. No avail. Slplugin.exe dies on the vine, even when set to win95 compat mode.
I was under the impression that the driver problem with the BF Killer2100 had been fixed with the latest driver patch, but since I am apparently not the only user with this problem still, I guess not.
If anyone finds an answer that hasn't already been quoted like twenty times, please post it here, thanks.
Oh, if anyone who works at LL wants to give a look at it, here's what I think is a relevant snippet from the .log file:

Thanks for any help. Seems to me this is an ongoing issue.
