failed to run minimo 0.007 on Axim X50

I downloaded 

http://www.meer.net/~dougt/minimo_ce/MinimoCE_0.007.zip

from 

http://weblogs.mozillazine.org/dougt/archives/008595.html

to Dell Axim X50 CF card.

it can't load, with Error message:"A critical component is either
missing or cannot start because program memory is unavailable"

Try adjusting program memory, didn't work.

Then downloaded 0.005, 0.005 works.

Is 0.007 supposed to work on my kind of PDA?

Thanks!
