Gnumeric won't open after attempting to open .xlt

I downloaded an .xlt file from officedepot and clicked on the file.
Gnumeric tried to open and failed. I then tried to open Gnumeric through the
menu list and it still failed to open. If it is trying to open the last file
attempted ie. the .xlt file, then it won't open at all.?
Is there a config file that I can modify to remove the last file entry?
