Cant burn a CD

I mean am I really stupid or what- have been doing the click and drag thing
for twenty years but Vista wont let me burn ANYTHING to a CD no matter if its
c;ick and drag or copy to..or whatever-and yes I formatted theCDs like its
asks- no prob burning to a DVD using the enclosed SONIC software with my new
HP Pavallion laptop dv5020us- WHY AM I NOT ABLE TO BURN CDS - I get such
error messgs as the file is bo longer in that place-whatever does that mean-
