I have just had a Blu-ray Burner installed by the local computer shop. When I booted it up it came up with a message that "WINDOWS HAS BLOCKED SOME STARTUP PROGRAMS" I started up PE7 and instead of having my thumb nails I had the generic icon. It asked me to find a particular file however when I found the correct file it has a message "THIS TYPE OF FILE IS NOT SUPPORTED OR THE REQUIRED CODEC IS NOT INSTALLED"
I am running Vista
Any help greatly appreciated.
