Files Will Not Copy

PROBLEM SEEMS TO BE SOLVED - Sorry for inconvenience.

I tried to "seach" this problem here, under copy, move, cd, etc, to no avail, perhaps there is better selection of search words to try.

If not, below is description of difficulty.

XP Media edition:

I can copy/move files to folders, but cannot copy or save to CD, getting message, "Windows having trouble copying this file... What do you want to do, etc"

Occasionally, if I turn off computer for a time and restart, it may copy...but likely not. Moreover, I can read and copy files from disk to my computer files, but not the other way-round...

I "cleaned" the CD read-write with "cleaner" disk.

I have upgraded my XP etc from MS site and it is set to auto upgrade as well.

The problem is recent.

Any suggestion is welcome...
