Please send an email with as much information as possible, including the build number obtained from the Help:About dialog, to support@FSSoundStudio.com.
If the problem is related to a specific sound.cfg file, attach it to your email and send it along. Don't hesitate to include any problematic .wav files as well -- in order to fix a problem we need to be able to reproduce it!
If FS Sound Studio crashed, then capture the screen dump, and in particular the stack dump and email the data. It is not obvious, but you can select the text on the system dialog that shows the error and paste it into a text editor, such as Notepad. Select the text with your mouse and use Ctrl-C to copy the text to the clipboard. Use Ctrl-V to paste it into your text. Make sure you indicate what FS Sound Studio was doing when it crashed. Here is a sample stack dump:
FS Sound Studio caused an invalid page fault in module KERNEL32.DLL at 0123:aff75411.

Also, if you're familiar with the use of the Dr Watson tool from Microsoft, this can capture the state of a crashed program and generate a detailed failure report. Please email the report to the above address. More info on using Dr Watson can be found at Microsoft Product Support, Knowledge Base article 275481.
