canola just can not run now, even though it is installed without problem. (on n800)

canola beta-2 installed according to the guide on indt site. (repository settings are ok. installation appears to be ok, both one-touch install and app manager install). after restart n800, run canola and it popup window displays "canola loading" a while then disapear, but canola doesn't run.

un-install and re-install can not solve this problem.

canola has worked fine previously on this n800 machine before re-intallation of canola and other programs(mplayer, mediastreamer,kmplayer,etc).

anybody can help? thank you.
