2.3.1 release GCopyright error - pls help

[ferrogrus]

Hi,
Pls help. I downloaded Win32 release 2.3.1. It worked fine until recent. Then it stopped showing the map, with the error message in place of map:
**************************
Sorry, could not initialize Google Maps
Error name: TypeError
Error message:`GCopyright` is undefined

1. isLoaded():true
2. GBrowserIsCompatible():true
3. isCompatible():true
***************************

Platform: Win Xp Sp2, 32 bit.
No problem to open G.Maps in IExplorer or through other applications.
Another comp connected to the same internet connection (but with win7) opens R.Converter fine.
Java installed and re-installed.
Can anybody help?
With respect to the community,
Stan
