I don't know but check the language region to see if changed it from north American English to uk .English if so set it back to north American apply and see if it resolves ???

1.In the Windows XP standard Start menu, click Start, and then click Control Panel.

In the Windows XP classic Start menu, click Start, click Settings, and then click Control Panel.
2.Double-click Regional and Language Options
 
Thanks for the reply, not working though, changed regional option to united states and in advanced tab to english united states, restarted and the hotkey still triggers the Euro symbol.
