I know the symptom you see is not what is described in
http://social.microsoft.com/Forums/en-US/money/thread/636e154a-9693-48a0-ab38-65627d192f6a but I would seek out the modified Mnyob99.dll file and put it into your "C:\Program Files\Microsoft Money Plus\MNYCoreFiles" folder. I replaced
my Mnyob99.dll file, even though I was not getting a crash. The nature of the bug seems to me seems to suggest it could do odd things.
Another thing to consider is to copy Sample.mny from your Money install folder and open that copy. If that works fine, then I would move on to making a repaired version of your Money file with
File->RepairMoneyFile->StandardFileRepair level 2
In fact, you could just move to that step to see if it helps.
If worst comes to worst, you can install Money Plus Deluxe Sunset. It will not do direct online accesses, but it should get you going if the other steps do not.
