Version Notes...

v1.7.89

• Fixed a problem when trying to race saved races after we increased the 1000 leg limit imposed when courses were built by hand.
• Removed the Modem Racing feature due to known bugs and incompatibilities with current modem variations.

v1.7.88

• Increased the 1000 leg limit imposed when courses were built by hand. This will allow courses built by the DeLorme Topo USA - RacerMate Edition and the Topo Course Creator program to run. Please be aware that DeLorme course data can have up to 40,000 legs or more of data, and as such the course may take a few seconds to load.

v1.7.78

• Added Windows 2000, XP, and USB-to-Serial Adapter Compatibility
• Removed the Direct Connect Option for Rider Two, which was a test function anyway. 
• Relocated the Options SpinScan Source to a direct sub-option of SpinScan. 
• Altered the Test Comm Ports program to ignore errors in the system and only produce the report - no "file not found" complaints or errors. 
• Moved the Options Enhanced Graphics to the Racer.ini file to minimize the potential of setting Enhanced Graphics on low graphic capable PC's. Power Users can still turn this option on by editing the Racer.ini file. 
• Program won't crash now if the courses or saved race files are in folders other than the PC1 folder.

Known issues:  

• Some users may experience new problems with modem racing communications. We're still working on a fix for this.
• Belkin Model F5U409 USB-to-serial adapters have experienced some problems communicating properly with CompuTrainer Software.  If one is needed we recommend getting something other than this brand or one that is offered from RacerMate here.
