The sample rate mismatch error is fairly easy to fix without having to reinstall drivers. These are the instructions I send out when we come across this issue:

Quote:
Right click on the Windows Start menu and choose Run, then enter "control mmsys.cpl" and press OK. This will open up the Windows Sound control panel.

Under the Playback tab, choose your default audio device (with the Green checkmark), then click on Properties. Go to the Advanced tab and choose 16-bit 44100 Hz (CD Quality) and click OK. If there is only the option of 24-bit 44100 Hz (Studio Quality), choose that instead. While we're here, uncheck the option to "Allow applications to take exclusive control of this device".

Next, do the same on the Recording tab with the device that has the Green checkbox. Click Properties, go to the Advanced tab, and choose 16-bit 44100 Hz (CD Quality) and click OK. If there is only the option of 24-bit 44100 Hz (Studio Quality), choose that instead. While we're here, uncheck the option to "Allow applications to take exclusive control of this device".

Once that is done, click OK on the Sound window, then go back to Band-in-a-Box/RealBand/PowerTracks and make sure it is working.

Windows Updates often resets driver settings, so this is something that can happen often.
