mapping keys in version 0.11.1 on nokia E65 went wrong

[UltrasHapoel]

I've installed version 0.11.1 and tried playing simon 1.
at first, the mode changing worked (0+1, 0+2, etc) while I
didn't even understand what it is. later I mapped the keys
in order to play simon. when I wanted to save the game I found
out I needed the ENTER button which is available after changing
the modes with 0+1. I tried doing it but it stopped responding
to the keys combinations (0+1 and etc). I tried remapping all
the num keys and leaving them empty ("none") but it didn't
work. then I uninstalled and replaced v0.11.1 with
v0.10.0 & v0.11.0 which worked fine (this time i didn't remap
the keys...) but when I unisntalled them and changed back to
v0.11.1 the problem came back without me remapping the keys.
Does anybody know how to reverse it so the "0+1" will work and
I can use v0.11.1 again?
