Managed to get it sorted. I forgot to set it to run as Administrator, plus I had some corrupted saved files in My Documents SH3 Folder. Deleted these, then did a complete reinstall to C:\Ubisoft instead of Program Files (x86). Automatically, SH3 points you to Program Files (x86) so you have to direct the install to the C drive yourself. However on inserting the DVD for SH5 it points to install it to C:\Ubisoft. I think since Windows XP, newer games seem to always point to C:\ instead of program Files.
I was surprised that SH3 would run on Windows 8, being it's an old game by modern standards, but as long as you right Click the exe, click on Properties, then click on Compatibility at the top, then tick Run as XP Service pack 3 and tick the box Run as administrator, then click Apply before closing the Properties Window, SH3 will run ok on Windows 8. So there is life in the old dog yet for the foreseeable future.
I suppose it is the same for Vista & Windows 7 operating systems, but I have only had XP previous to this Laptop.
Anyways, I am back on the high seas again. Starting a New career from 1939 - with the 7th Flotilla. Using SH3 GWX V3 Gold,SH Commander V3.2 and GWX compatibility cfg for SH Commander.
Next I am going to install some more improvement mods and get it as good as I can from the many mods now available.
Thank you guys for your answers to my problem. What would we do without the Subsim forums. More than likely

Cheers
