Hi Mike,
First off, I apologize for any waits you may have had with the Tech Support Queue - we're going through a staffing change and will be adding additional reps in the coming weeks. However, it is unusual to have to wait more than a minute to speak with us; in fact, as I type this we have open phone lines.
What we have determined when the CAPN crashes inexplicably, it is usually due to one of the following reasons:
1. An bug in a older version of The CAPN that has since been corrected.
This is the case 80% (or more) of the time. Thus, the suggestions to try 7.5 and then 8.3. In fact, we will be happy to unlock version 8.3 for ANY customer who has a problem that it may correct.
2. A problem with corrupted routes, waypoints, or other data.
This is why a Custom Uninstall is an important thing to try. A Custom Uninstall removes all data - which leaves everything "clean" and without corruption.
3. A problem with bad, outdated, or incompatible charts.
This is one area you may want to try. Delete any and all charts from your HD and try the CAPN. If it works correctly, the problem is somewhere with the charts.
As an aside, we are about to release a new chart library that is specially designed for use with The CAPN. The library will include the latest CAPN software along with 18 DVDs of Raster, Vector, Photo, and 3D charts for all US waters. The upgrade price will be $149.00 - an incredible bargain. We're doing this so that all of the loyal CAPN customers can receive the latest software and charts - which will hopefully correct many of the various difficulties that have transpired in the months leading to (and immediately following) the sale of The CAPN from SAIC to Maptech in May, 2006.
4. Windows Compatibility Problems
It is possible that the errors you are experiencing are due to some compatibility problem with Windows. Thus, I recommend the following updates:
a. Obtain the latest Video Display Driver for your computer or video card manufacturer. Visit the web site of your computer manufacturer to download and install the latest video display driver. The CAPN is very dependant on this driver and it is not uncommon for updated drivers to correct these sorts of issues.
b. Obtain the latest "DirectX" from Microsoft.com.
Like the Video Driver, Microsoft is constantly making improvements and repairs to the component of Windows that handles video display. This component is known as "Direct X" and updates are available from Microsoft.com
Give these ideas a try, and if they don't work - reinstalling Windows could certainly remain an option. However that is a major undertaking unless it is really required. If you do go down that road, we'll be happy to re-register your copy of The CAPN - given your situation and history.
Please let me know if I can be of assistance in any way.
