What happened is that I tried delete a program by changing the program to open with itunes- now I know that it ain't the best way to delete a file but now I'm stuck in this situation. Now I don't know which program is suppose to open in default, and its a .dat file extension and the program that it is suppose open had picture of two nuts(that's all I remember). I have windows vista home premium.
Please, any help will be greatly appreciated.
Thanks
