I have the same problem with the latest version.
I was using version 4.06 for a while without any problems. But after I installed the new version, I get the same error. I am trying to burn ~110 MB data onto a CD-R.
I tryied with 5 disks but no chance. Then I downgraded to version 4.06 and have no problem.
There should be something wrong/missing with the new version.
Note: I am using with the command line parameters.
