I installed a valid copy of XP Home but after updating Windows I got this error message when logging back on after installing SP3:
"the license key is not valid on this media, please reinstall windows" error code 0x80040509
The COA is an OEM license & was bought from a well known software stop site ;) & the CD is a standard gold XP Home CD. Can anyone shed some light on this issue for me please?
There's info on the M$ site but no replies to questions sadly :(
