Component not registered correctly error

I don't know what happened, but MSFLEXGRID control is not registered correctly. Every project I have with this control gives me this error message. I tried installing SP3 again, but that did nothing. I need help!

This might be completely wrong but I had a similar problem with threed32.ocx
What I found out was that on the VB5 and VB6 cds there is a subdirectory called tools.In that there is another directory called components ot something like that.In there is a registry file/some ocx's and a readme file.
Basically I just copied threed32 from there and imported the reg file into the registry and this fixed my problem.
I can't remember if the flexgrid is one of the ocx's but it might be worth a look.
I suppose the best way to find the directory is to do a search on the CD for *.ocx
Hope this is of some help
