After I tried the version 9 on several PCs without success to backup on CDs and DVDs I tried to install the version 9.1 Workstation. But this time I can not even install the software: it says all the time I should register first (I have allready done that) and it says something about a license server and I tried it with the license code software but there I have the same problems. Who can tell me how to install the trial version of this software? Who has experiences in backups on DVDs? Thanks a lot!
