Saving a .dat file Compression Problem

[subtorn]

When I finish editing the game file to my liking (Star Trek Away Team is the game), I get this error message when I try to launch the game:

'Compressed Zip File Found
Data.DAT has been created using compression. All zip files must be created with compression set to none.'

I've used 3 different hex editors and get the same results no matter which mode I edit in (direct editing or just saving after editing). Any suggestions?

Are you using Game Editor?
