Problems launching steam

I have a problem launching my cs, and my steam as well.
Everytime i double click steam this error pups up:
“Steam.exe (main exception)): CMuliFieldBlob(pSerialized): Partial field header at end for record”

I’ve tried to uninstall my steam but it still doesn’t work. Any one who can help me out here?

You can try closing steam and deleting the clientregistry.blob file in your steam directory.

Also, you might have luck searching the steam forums if that doesn’t work:
