Error (ERROR_MISSING_OBJECT)

I have just started trying to use gallery and I am having some issues. I am getting the following error message when I go to the main.php page:

Error (ERROR_MISSING_OBJECT)
in c:\inetpub\wwwroot\gallery2\modules\core\classes\GalleryUrlGenerator.class at line 278 (gallerystatus::error)
in c:\inetpub\wwwroot\gallery2\main.php at line 95 (galleryurlgenerator::parsecurrenturl)
in c:\inetpub\wwwroot\gallery2\main.php at line 47
in c:\inetpub\wwwroot\gallery2\main.php at line 40

I have tried to reinstall, go back through the config wizard, etc... and no luck. I keep getting the same error message. Configuration information below. Your help is greatly appreciated.

Thanks in Advance....

Give us your Gallery/webserver information to get a faster answer.
Get this information from the PHP diagnostic (in the configuration wizard).
Gallery URL (optional but very useful):
http://megatron.idlegames.net/gallery2
Gallery version: 2.0-alpha-3
Apache version:
PHP version (don't just say PHP 4, please): 4.30.10
Graphics Toolkit: ImageMagick 6.1.8 Q16
Operating system: W2K3 Enterprise Edition
Web browser/version (if applicable): IE 6

Alpha-3 is getting quite old. Would you please try installing the latest nightly from scratch and see if you can reproduce the problem? You should delete your current gallery and data directory and start all over from the beginning.
