KWORLD PCI card problem

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.

 

Did you install the correct drivers you can get them here
http://www.nodevice.com/driver/company/kworld/TV_Tuner.html
or you can run a scan from the site for driver problems

 

Yes installed the correct drivers and under device manager they show up correctly

 

I have now done a complete fresh install of Windows Vista and then reloaded the Kworld software. As soon as I scan for channels I get the message "Invalid floating point operation".
Have tried contacting KWORLD technical but they don't answer.
