Here is the resolution to my particular situation.
MacAfee Issue
The email scan function of MacAfee virus protection blocks the communication from your dive computer to your PC. The instructions below will tell you how to circumvent the issue.
Hit CTRL-ALT-Delete on your keyboard. A menu will pop up; select the Task Manager tab. Then, from the Task Manager window, select the Processes tab.
Now look down the list of processes and find the one labeled McVsescn.exe. Click on this process and end it, ignoring the Windows warning about ending it.
Your SmartTrak should now work. Go directly to your SmartTrak program and attempt to download the dive computer. If it doesnt work, try it a couple more times, experimenting with different positioning of the dive computer and IR reader. We found that getting dive computer within ½ inch of the reader works the best. If after a couple tries and it still doesnt work- Contact 1-800-382-2211 SCUBAPRO UWATEC Tech Support Monday Friday 8-5 Pacific Standard time. Please be sitting at your computer when you call.
Be advised, the Process you ended is the MacAfee virus scan for email and the PC should be re-booted prior to viewing email. Rebooting will bring back the Process and protect your PC from emailed viruses, but remember to end that Process each time prior to downloading your dive computer.
Happy downloading!
