I have a KWORLD PLUS

Question

I have a KWORLD PLUS TV HYBRID PCI (DVB-T 210SE) TV card which I used on my previous PC running Windows XP.I have bought a new PC running Windows Vista and have installed the TV card. I also installed MCE Encoder at the same time (maybe I shouldn't have done).When I scan for analogue channels the application seizes up and I got a warning red box saying "Scheduled agent setting file is corrupted... (2006)"I then got a box headed Analogue TVR which said "Invalid floating point operation".I have tried uninstalling card and MCE encoder (which won't uninstall all files as it says they are locked).I've installed the TV card again but still can't scan channels.Can you help?
