I right click on a file,then i Go to { OPEN WITH } then go to Choose default Program here comes My Problem, here is what it says to me, { this file does not have a Program associated with it for performing this action.Please install a Program or,If one is already installed,create and association in the default programs control Panel. Now i have gone to Control Panel and Opened the Default Programs and there is NO place to add an association to OPEN,WITH it wont open the File Manager or Program manager that It usually opens or what ever is associated with it,Now the Only thing i did that It stopped working I can see is install Winamp the newest version and I think it was a 64 bit program,but that is my Only problem at this time.I just bought this Computer the 28th of February and this has happened and I did the Backup BUT i really don't want to restore the whole system just because of this But If so that will be it.But any help will be appreciated.Thank you.
