Hi... I solved this problem by going to "Folder Option" ... "File Types"...
Since I could not get it to change by using the "Change" button... I just clicked "New"... and did the association again....
It worked! The only thing now is that, when I double click... it says that the mat file is not a valid win32 application. However, when I right click, an additional option is added to the popup.. "Import into Matlab"... works ok for me :D
