Well, I have many important photos saved on writable CD's.
I took the photos, I bought the Gateway computer, I bought the blank CD's, but now when I try to view or save to my CD's, I get a warning that the CD's are expired. (?)

printscreen attached:

So I can't even use these CD's now?

 

never heard that before cd's having exp. date.

 

maybe the disc is full.
try using nero
