Bump on 11/17... Here's an update:

Nothing has worked so far. The list of ideas Blizzard's tech support (I'll spare the long rant about how slow and ineffective they are) has provided is as follows:

• Them: Update your drivers. 
• Me: Ok.... still doesn't work.
• Them: Thanks for contacting us! Take this survey and let us know about your experience.
• Them: Hey, why didn't you update your drivers? 
• Me: I did already, what's next?
• Them: Thanks for contacting us! Take this survey and let us know about your experience.
• Me: Umm... You still haven't helped me.
• Them: Well that's odd. Are you using more than 1 stick of RAM? If so, remove all but 1 stick of RAM and try that.
• Me: Ok... Nope, still doesn't work. I've tried multiple combinations of RAM sticks and motherboard slots. Always the same error.
• Them: Thanks for contacting us! Take this survey and let us know about your experience.
• Me: Are you f'ing serious? Can I have a phone number to call or something? Wrath has been out for several days now and I'm getting angry that I'm paying a subscription and you're not being very expedient about helping me...
• Them: (No response, going on 2 days now)

As for the feedback and help you guys provided here, I tried first to just upgrade with Wrath when that came out and it gave the same memory error on the Blizz installer. So, I did the full uninstall, rebooted, and tried to install from scratch. No dice, same memory error on that Blizz installer. For the first time I saw a similar error last night for my web browser when I was multitasking and surfing the net, but that wasn't repeated when I reopened the browser. I dread the notion of having to do a full reformat of my computer, but I think it's coming down to that.... Anyone have any lingering ideas of what else might work?

So I haven't been able to get WOW to load for several days now... I keep getting this error:

ERROR #132 (0x85100084) Fatal Exception
Program: ...\Wow.exe
Exception: 0xC0000005 (ACCESS_VIOLATION) at 001B:7C91302C

The instruction at "0x7C91302C" referenced memory at "0x00976A54". The memory could not be "written".

I've exhausted the Blizzard technical support knowledge base, done some searches on the Internet for help, and nothing seems to correct the issue. I emailed them, but their email support tech assigned to my case was slow to respond and is now out of the office for at least the weekend. With the holiday tomorrow I'm thinking it might be even longer before I hear back... Anyone seen this before? Any ideas what the hell is preventing my WOW from loading?

Nothing else on my computer is impacted. Only WOW and associated files (including the Repair.exe file). They start to open, then immediately shut off and display the same error. The Launcher opens for 1/10 of a second then shuts off, no error. It's getting obnoxious, because usually I can figure this stuff out! Any experts out there who can help me get back online? I've been playing XBOX and watching DVDs, but it's getting boring! I want back in!!
