Updated Info For This BitComet Error

I didn't notice the introductory post before (Whoops!). Here's a revised post on this strange issue;

• I'm using version 1.42.
  
• I have no idea what type of internet connection I'm using, though I doubt that's important for my particular dilemma.
  
• Don't know anything about my router, but again, I doubt it's important to this.
  
• Running Windows 7 Professional (64-bit). Have AVG Zen (I guess. Half the time it says AVG Zen, half the time the word "Zen" is nowhere to be found), build 1.82.2.30772.

PC Specs:

• Manufacturer: Dell
  
• Model: Optiplex XE2
  
• Processor: Intel® Core™ i3-4330 CPU @ 3.50GHz
  
• Installed Memory (RAM): 8.00 GB

Now with all of that out of the way, I'd like to explain the situation itself. I've had this computer for over a year now, and at least a month after getting it, I installed BitComet. It worked perfectly fine the whole way through, but about a month or two ago it stopped working. All of a sudden whenever I open it up, I get this error. I've already reinstalled it, but that didn't help.

I believe this started sometime after I got a new graphics card, though I can't see how that would cause a... non-graphical (?) program to stop working. If anybody has any insight on what might be the problem here, I would appreciate it.
