Backup won't accept file name

[oldebh]

Running Windows XP Home ED. with Service pac @ and keep updated autmatically.  System is 6 months old with Intel Celeron 2.66 GHz processor 70+ GHz hard drive, CD/DVD and HP printer. 

Want to backup my files so a few weeks ago downloaded Windows Backup .  Tried to backup all personnal file today to a Dvd disc in my system D drive.  Using Wizzard to do this and when I get to the screen that asks for a file name, it will not accept any input I use for a name suchas "userfile" or "Oct-07files".

Any suggestions/ideas on what I'm doing wrong?

Why don't you try placing your backup on your HDD, then burning it to your DVD. I suspect that it won't backup to your DVD drive because the size of the backup is unknown. I have run backups and placed them on my second HDD with no problems.

Does Windows XP Home ED not have Windows Backup, under Accessories, System Tools?  Surely, it does.  So, why did you have to download it?  Where did you download it from?
