BitlLocker error encrypting drive after decrypting

  Starting BitLocker dialog box displays:  "The Group Policy settings for BitLocker startup options are in conflict and cannot be applied."

  I had BitLocker enabled on the C: drive on my PC with the TPM enabled in the BIOS and it worked, but I could not get it to wirk with TPM and a PIN.  I had changed the Group Policy "Allow additional authentication at startup" to Allow TPM and Require startup PIN with TPM, and run:

  manage-bde -protectors -delete C: -type tpm
  manage-bde -protectors -add C: -TPMandPIN

  Nothing worked - every combination I tried for different values for the GPO settings and manage-bde commands with BitLocker suspended or active returned a GPO error.

  I turned BitLocker off, hoping that if I enabled it with the GPO set correctly before BitLocker was enabled, it would work with a PIN.  Now when I enable it, I get the GPO error above.  I have disabled the GPO setting, and still get the error.

  Is there any way to get BitLocker to work at this point - other than reinstalling Windows or restoring from a backup?  At this point, if it will not work with a PIN, that is ok.
