Technisat SkyStar USB 2 HD CI not working with 5.1, 5.0!

[dimlog]

After installing 5.0 or 5.1 initially seem to work but nest time the DVBViewer does not work!

I have no problems with DVBViewer TE2 which followed the card (Technisat SkyStar USB 2 HC CI).

I would like to go back to the version I initially bought 4.6(?) and try again but could not find it on the site. I tried with 4.9.6 but the result was zero again.

The scanning process was run successfully and I created a favourite list but in the next boot it showed no signal at all, very strange.

Any help or suggestion very welcome.

In DVBViewer i recommend go to "Options-->Hardware-->Scan Devices"
