IO,
It is an OEM license, not an upgrade or retail license (£90, rather than £160 or £250). This is probably the reason for failing the WGA validation process.
This product is intended for system builders and small OEMs (Original Equipment Manufacturers) who manufacture computer systems and preinstall Microsoft OEM system builder software onto those systems.
Its use is subject to the OEM System Builder License Agreement that is affixed to the side of all OEM system builder software packs. The system builder who installs the individual software license and distributes hardware units must provide end-user support on terms at least as favourable as the terms under which the system builder provides end-user support for any fully assembled computer system. The system builder must place its support phone number in a noticeable location in the fully assembled computer system help files or end-user documentation.
