If your computer has experienced a operating system error commonly referred to as the "Blue Screen of Death" or BSOD when using Tracker, and you are also using a USB-to-Serial (Serial-to-USB) Adapter from companies such as Belkin, IOGear, Keyspan, or Radio Shack. 

This problem is caused by an error in the implementation of the drivers for the user's USB-to-Serial adapter.

Stop: 0x000000D1
or
DRIVER_IRQL_NOT_LESS_OR_EQUAL

"The Stop 0xD1 message indicates that the system attempted to access pageable memory using a kernel process IRQL that was too high. Drivers that have used improper addresses typically cause this error.

Stop 0xD1 messages can occur after installing faulty drivers or system services. If a driver is listed by name, disable, remove, or roll back that driver to confirm that this resolves the error. If so, contact the manufacturer about a possible update. Using updated software is especially important for backup programs, multimedia applications, antivirus scanners, DVD playback, and CD mastering tools."

You may try to uninstall and reinstall the appropriate drivers for the adapter in question, or may be forced to attempt to use an adapter from a different manufacturer.  JTECH recommends connecting Tracker Legacy hardware directly to the computer via serial port as directed in the Tracker user manual.
