Hi guys, thanks for the quick responses.
I have just done a full uninstall and reinstall, except for all my mods, and GWX 3.0 and SH3 commander are so far running fine.
I wondered if you could tell me how I do a BCDedit privateer, sorry, but I've never heard of that before and it would be very helpful if I could use more than the 2GB of RAM, just to make sure that that's not the problem before I start disabling any mods that are struggling because of my system memory.
Thanks
