MapsetToolkit won't install in MapSource

[RCinSTP]

I am using GPSMapEdit to make maps and MapsetToolkit to install the maps to MapSource and then to my GPS. It worked for me yesterday on a different computer.
But today MapsetToolkit runs through the process and the window pops up "Convert completed" but the new map does not show in the Mapset Installed window.
MapSource is installed on my C: drive. MapsetToolkit is installed at C:\MapSetToolKit_v1.77 and cgpsmapper is installed at C:\MapSetToolKit_v1.77\cGPSmapper
I also tried installing with MapsetToolkit with the Install button in the lower-right but I get the message "Cannot insert a Mapset in Mapsource"

I have the .img .typ .tdb .reg .mdx .mp files all in the C:\MapSetToolKit_v1.77 folder.

Any ideas of things to check or what I might be doing wrong?

=========== SOLVED ==========
If you have the same problem that I mention above. I uninstalled MapSource, then reinstalled MapSource and then it worked fine.
