Import Tracks feature not working in 2.613

[Canton]

I have a strange problem in that when I try to use the Import Track feature, select BIN as the file type, click on select folder, and go to the folder where I have these files stored-- I cannot see any of them, and in fact the "choose folder" window that is open has a strange looking drop-down in the bottom of the window that has no functionality. I CAN achieve results under the Play tab by using select folder, Add Track, and selecting BIN file type. Of course this only allows me to play the selection to confirm it is a good file. I can't burn them. Any ideas? I tried re-loading Microstudio thinking maybe a file was corrupted, but the same condition exists.
