DW5.5 crashing frequently (both 10.6.8 and 10.8.5)

Question

Hello. I'm having problems with Dreamweaver CS5.5 crashing frequently while I'm working.
Sometimes I'm saving, sometimes I'm not even working in the program, but it is open in the background and it crashes.
I've tried to research causes online, but I'm still stuck.
I recently upgraded to Mountain Lion from Snow Leopard, in large part because of DW crashing, but the crashing has not stopped.
I have replaced the preferences, but still no change.
I read that it might be related to my font management software, "Suitcase Fusion", so I updated that, but still no change.
Then I read it might be b/c I am running 2 monitors from a video card that may not be able to handle it, so I tried using one monitor only, but still crashing.
I am reluctant to spend $ on s new computer for a better video card if I am not sure it will solve the problem.
Here is a link to 2 crash reports (the 2nd one starts on pg 22 of the PDF):

Below are screen pix of my computer info (I do have a second monitor hooked up -- not sure if info below shows that).
ANY HELP or advice would be MOST appreciated.
Many thanks,
Katie

Preran,
I haven't crashed now in almost a week! You have no idea how wonderful this is!
Thank you SO MUCH for your help!
Given that I just downloaded my Mountain Lion directly from the Adobe site, why wouldn't that version have included this patch?
It never occurred to me that a freshly downloaded versoin might still need to be updated.
Thank you again.
I wish I had asked for help much earlier -- when I was strugglng with this problem in 10.6.8.
