Deleted Microsoft User Data, now FileMaker Pro, EndNote Won't Launch...

Question

Yesterday I was trying to clean off my HD, and I was basically cleaning stuff out of Documents, Music, and Pictures. When I came across the "Microsoft User Data" I figured I don't really use microsoft apps, (have them installed but don't use them), I deleted that folder.
Now Word (2004) runs fine. But FileMaker Pro 8.0 Advanced, and EndNote 9.0 won't launch at all. Neither one gives any error message. They both bounce in the dock a couple of times and then just stop. I actually reinstalled EndNote 9.0 (an upgrade install), and it still doesn't lauch.
Can I get those files back? If it's not the Microsoft User Data, then what is the problem? If re-installing doesn't fix the problem then what can I do?
The only other thing I can think of was that I installed the security updates last night and iTunes 7.2. I can't figure how that could have done it but you never know.
FileMaker is key to my research (grad student in archaeology), and I'm crippled without it.
PLEASE HELP!!

Answer 1

What exactly is that data?
AFAIK, it contains the registration data for your copy of MS components. You'll get a better answer at the MS newsgroups: http://www.microsoft.com/mac/community/community.aspx?pid=newsgroups
Is there any way to repair the link or lost files?
Not unless you have a backup or want to expend bucks with something like Data Rescue.
Would a copy of the old User Data be found in any of my other accounts on the computer?
Not likely. It's probably user specific.
If I logged in to another user account on my computer and went and copied the MS User Data folder, and then replaced it in my main account would that have any effect?
Once again, visit the newsgroups. That's where you'll get better answers.
