TGEA 1.7.x trouble

Hello people,
Unfortunately, I have quite a large problem with the Barricade demo and TGEA 1.7.0. Strangely enough, this problem doesn't occur with the Forge demo or TGEA 1.0.3. The Application itself seems to load fine, however, when I get to the point where it goes to load a mission, the game will get stuck at "LOADING DATABLOCKS". Sometimes this will just get stuck after the loading bar has been filled, and sometimes when I press the load mission button, nothing happens.. I have noticed in TGEA 1.7.0 that if I activate another window outside of TGEA, it will sometimes progress with loading, but this is not very common. Sometimes in the Stronghold demo, I do not even get to the point where I can load the menu, rather, I get a black screen after the TGEA logo fades out. The only temporary solution I have found to this is to reboot the system, but I plan to sell my game, and I'm pretty sure my customers don't want to be rebooting every time they wish to play.

There is a link to a screen-capture of my console window after the button does nothing. If you request any more information please do so, I would like to resolve this problem as soon as possible.

My system specs are:

AMD Athlon64 x2 4200+
Nvidia GeForce 8800GTS 320MB
2GB of RAM
2 Monitors (Doubt this would cause problems)
Windows XP Professional (Corporate Edition) SP2
600W PSU

Now, I am currently blaming the inability to load on the fact that I usually have many applications open at once when I try to run any of the demos, and sometimes I find that closing tabs in firefox can sometimes let it load.

I would appreciate any help as soon as possible, please email me at: steven@motronsoftware.com , however I reccomend that you leave a follow-up comment here incase anyone else who has the problem can resolve it.

Thanks, demo looks great from the video anyway,
-Steve
