If it's only a band in a box problem it would seem that asking pgmusic for a fresh download of the program only should fix the problem. That IS possible. I had a problem with a function recently that has been identified, fixed, and I have a new version sent to me.
This is the most responsive company to deal with, and any problem you have is discussed, sometimes in a meeting, and then solved. Odd behaviours can be something in your system, but sending a new download of just the exe file should result in a fix IF it is related to the software.
Other problems, that are computer related, are obviously NOT a band in a box problem and need to viewed as such.
