I realized that Revit 2011 uses .rvt files vs. .rfa files. Since I removed 2010, I didn't have a program to open .rfa files. Once I reloaded 2010, I was able to open the .rfa files in 2011, which then automatically converted them to .rvt files.
Lesson of the day; when upgrading to 2011, leave 2010 installed.........just in case.
