Sure, try:

It's more centered around what you described - but I hoped a
reinstall might fix it (more completely) and any other issues you
might not even know you had.
Now knowing your SP level, the fix suggested ("to fix the problem,
upgrade to Service Pack 3") makes sense now, but you can try the
DLL registration first if you want.
Let everyone know how it goes!
Oh - addendum - I agree with PA Bear; if you still only have SP2 -
you should consider going to SP3 ASAP. If you have had trouble in
the past - I'm sure we can attempt to walk you through it and get
past all that.
