Well I don't know too, how should it help
... That's just speculations
. The problem of starting in ubuntu lies in config file 'Rainlendar-user_name'. If I open it with a text editor there is only number in it. What does this number mean? When the program doesn't want to start then I must to remove it and try again.
I don't know what this file is for but I think that in next releases the logic of starting program should be changed, because the popularity of the program is falling down.
Even I'm loosing my patience, and I'm using it for 2 years... It would be a pity because I don't want to stop using it.
