DevilJeka,
As long as it is running in an HP machine it should work. Please go to the HP site and download the specific version for your machine, you may have gotten the wrong one. It can also be reinstalled from the recovery CDs.
If neither one of these work, give HP tech support a ring. They will be able to point you in the proper direction on their web site. We can not provide downloads directly to consumers for the HP products.
