Can't start the programme

Hi one and all ...i run W7 64-bit and in spite of trying the f8 trick and trying the DSEO programme to try and get round the unsigned driver issue i'm not making a lot of progress. When i try to start TP a couple of errors appear as follows: 0x80070005 0x80070002I have fs9 installed on a partition (G) of my hard drive and asked the proramme to install the caches onanother partition (F) ...For the first time in my FS career i now have a machine that handles fs9 with ease so it's very frustrating to be unable to unlockthe goodies TP brings to the sim ... hoping some one can help ...Alan
