CopyToDVD Writer error

Newbie help requested… would really like to test this software but I wonder if writer problem described below is b/c it is a trial version that I just downloaded:

“No writers found for the system” error message.

Is this because it is a trial copy? If I go into drivers-check off main menu and check driver, both my drives are found. If I go into tools-vsoeraser, bulldown box for writer shows empty. If I go into settings and de-select Prompt for writers, also nothing shows in pull downs.

All other DVD software on my system is working fine. Sonic can burn without a problem, and DVDdecrypter performs without a hitch. Please advise, I’ll buy if I can get it to work.
