No App Icons on Menu

I just installed the base version of PortableApps and placed my pre-existing apps (PortableFirefox, Thunderbird, etc)in folders next to the menu folder as explained in the instructions. When I refreshed the menu, the apps show up in the menu and they run fine but the menu only has generic system .exe system icons, every app has the same one! The right-side folder icons for documents etc are fine.

Any suggestions?

ps just to see if I had improperly moved the folders, I actually downloaded and installed one of the .jar.exe files...that one shows up on the menu but it also only shows a generic system icon.
