Gegu,

Welcome to the forum and to Band-in-a-Box. If you would like to help PG Music resolve the issue, there are several text file logs you can copy and post in the forum.

Use Notepad to create a blank text file. Save the blank file under the name "PreserveAllFiles.txt. Move the PreserveAllFiles.txt file to the BBPlugin directory at \bb\BBPlugin\PreserveAllFiles.txt.

The blank file instructs the plugin to keep all temporary input-output files. These files normally are generated on the fly then discarded. This allows you to look and copy them.

Some of the temporary files include:
BBoutput.txt
RBResults.txt
BBInput.txt
BBSong.txt

There are two locations where you may find useful information regarding crashes. They include:
\bb\Data\bbw4_PlugInLog.txt. Backend Errors messages can appear here. Backend is communication between the main Band-in-a-Box program and the plugin.
\bb\Data\bbw4_64exe_FlashMessageLog.txt
Flash messages are the yellow and green pop up messages that briefly appear. The Flash message file will show some error messages.
