Hello. On the standard version of Windows 7 ProgDvb 4.92.4 works great. When I try to put the pro version I get an error.

WinLicense
An internal exception occured (Address: 0x77cbfc77) Please, contact prog@progdvb.com. Thank you!

I want to use this version because it is more accessible than 6x versions of screen readers for the blind and visually impaired.
