uTorrent not opening

[Lumberjerk]

I have been running uTorrent version 1.4.2 beta build 428 flawlessly for some months now. I just got back from an extended trip and when I opened up uTorrent, it prompted me to upgrade to the new 1.7.2 build, which I did. Everything ran fine until I closed the program out.

Now, when I try to open it, nothing happens. Nothing that I can see opens, and nothing resembling uTorrent is displayed in the Task Manager. I redownloaded the 1.7.2 installer file, but even that will not open.

Anyone encounter anything like this or have any clue what to do?

Does the problem persist after a reboot?

Where did you get this "installer" for 1.7.2?

[Lumberjerk]

Yeah, rebooting was my first instinct. No change.

Okay, "installer" is not the right word. I honestly can not remember if, after uTorrent prompted me to upgrade, it downloaded/ran the upgrade itself, or if I downloaded from this site and ran it manually. Either way, I didn't get it from a third-party site.
