lordmiss informed me that the MacHeist flag gets set, even with the language incompatibilities. 3.04 should see the flag and not bother you.
"but It wouldn't work all the way crashed." is very different from the language issue.
The language sets issue allowed MacDust to open, but not show the main window, but it had plenty of time to write to the preferences.
Go to your preferences folder ( ~/Library/Preferences )
and look for com.theapplegeek.MacDust 3.plist
If it exists, email it to me; if it doesn't exist, still email me.
