Sonic MyDVD LE trouble

over the past few days i have noticed that my sonic software seems to drastically slow the computer down and i've had to restart the computer only to find that some program is still running (get the "end task" box)

however today when i started to open sonic the windows installer immediatly popped up and tried to install sonic but it said it couldn't find the disk... i tried the sonic disk i got with the computer but it still said it couldn't find it... when i went to cancel out the installation i discovered the entire program IS still on there, yet every time i try to start it i get the installer again

does anyone out there have any ideas what could be causing this and how i might fix it? i would appreciate greatly any help you can offer Thank you!

 

Try un-installing it first.

 

ok... thanks... i'll try that ... and if it's still giving me problems then i'll be back
