Hello flashgordon,

In the Options | MIDI Devices window,
1. what is currently selected as your input and output driver, and what other MIDI output options are listed.
2. is the "re-route to default dxi synth" box checked?
3. If so, what DXi synth is selected.

In the Options | Audio window,
1. is your audio driver type ASIO or MME?
2. Click the [driver] button... what are selected as the input and output ports/drivers?
3. In the ASIO Audio Drivers dialog (if applicable) what is the selected ASIO device ?
4. In the ASIO Driver control panel (if applicable) what is the latency of buffer size set to?

In the mean-time, please try reinstalling the program, like this:

1. You don't need to remove your current RealBand folder.
2. All you need to do is run your RealBand setup file (if it's part of the Band-in-a-Box 2008 installer, you can uncheck the Band-in-a-Box component), and install it to a brand new folder. I.E. in the "Select Destination Folder" setup screen, choose something like C:\RealBand_NEW.
3. Install the latest RealBand 2008.5 update patch (build 4).
4. Run RealBand, answer NO to the ASIO driver question, so that you are using MME drivers.
5. Setup your MIDI drivers and so on, then use the program for a while on NEW files and see if you continue to experience the same types of crashes.
