Bummer.
Not sure on anything else nor do I have an answer to your question.
I was just covering the simple stuff!
I'd guess you may be correct and a windows update messed with something. Seen that happen enough!
I guess you could try removing/reinstalling or repairing the various .NET versions you may have installed. That's about the only other simple thing I can think of.
Hopefully UPMan will see this and offer some advice.
I never messed with Sentinel under Vista so not sure if there is something specific to Vista that others have seen. Do you have another computer you can install Sentinel on so you can at least get things updated for now?
Sentinel has always been very stable for me on Win 7 and XP. I skipped installing it on Vista. I just booted into my XP partition which I've not booted for many many months and Sentinel fired up no problem. I then did all the windows updates and Sentinel still started fine. I don't have a Vista install any longer so I can't test the same on Vista.
Good luck and I hope someone will come along that may have a working solution! Sorry I don't have any positive ideas other than the simple things.
