bare with me here...when "my documents" is open, all my files/tunes including the one i cant open is under the "all files" (*.ctz, *.tun, and i think *.bin) drop down box under the drop down box that has the name of the file/tune. when i go to rename it, it just saves the renamed file/tune back in that same folder. even if i put a .tun behind it when renaming, it saves it in the "all files" folder. in order for me to change it to the *.tun folder, i have to be able to open it and "save as". im gonna try and mail it out to fubar tomorrow and have him open it, rename it as a *.tun file and send it back to me to see if that works.
