ProgDVB Pro x64 says BDA-Device not started

#1
ProbDVB Pro x64 says "(BDA) Technisat Mantis DVBS not started".

while ProgDVB Pro x86 functions perfectly.

i installed Windows 7 new, and then the upper Report came, when i started ProgDVB Pro x64.

it comes also, when i install a new Version of ProgDVB Pro x64 over the older one.

what can i do to watch DVBS with ProgDVB Pro x64 ?
ProgDVB 6.48.4
