Memory Issues Using Digital Gem Airbrush PLEASE HELP!

I am having trouble using the Digital Gem Airbrush with CS2. I have no trouble using it with lower resolution images but when I try and use it with higher resolution images (6144 x 4097) I come up with an error telling me I don't have enough ram.

I am using a P4 3.0ghz with 2.5GB of RAM, and when the error comes up there is usually about 1.5GB of RAM still available.

Has anyone got any ideas as to why this is happening, and or how I can get around the problem?

Does nobody else use this plugin?

I have same problem, but only wenn I have more pictures open i PS. Wenn ypu get that mesage try to apply filter again, it work sometime. Then I upgrade memory 1gb to 2gb and problem disepear. Try to apply filter with only one picture open in PS.

I've used it, but only with native 8-10MB files, without problems. However - any chance that you've tried to increase the size/number of the CS2 scratch disks?
