Support to set up Bit Locker on Vista

Hello, I do not have Bit Locker enabled on my IBM laptop (model UT0FVUK). When I try to enable it in Control Panel it tells me the following: ----- Your Trusted Platform Module (TPM) Security Hardware is not working correctly. The authorization data for the Storage Root Key (SRK) of the Trusted Platform Module (TPM) is not zero and is therefore incomatible with BitLocker. Click here to initiaize the TPM The drive configuration is unsuitable for BitLocker Drive Encryption. To use BitLocker, please re-partition your hard drive according to the BitLocker requirements. ---- The project is to simply guide me through enabling BitLocker by email/instant messenger/telephone. Thank you.
