DVDfab 5.4.0 beta error 115

First off I want to thank Fentago for a great software package DVD Fab is #1
I am new on the forum, but I have been using DVDFab Plat. since version 3. I have never had any problems using DVDFAB Plat. untill I updated to version beta (long waited for audio preview great feature).
Small bug in version beta, I get error 115 failure to finalize, however my burned disk plays fine, just a small annoyance since I usually will do two copies with this error I have to rerip instead of just going straight to burn again, hope this can be fixed for next update I reverted back to version I know I will love this new preview system
again thank you for all of your hard work
