No, you didn't screw it up for "nothing" as there was some problem with your

The backup you have on DVD requires that OneCare be installed to restore data

If you still get the 0037 error, see if the information in this KB article
helps:

(the 0037 error means that the winss component is failing to install, the 0029
error is a generic roll-back error)
If not, please contact support:
