lottanzb inactive menu

Hello,

I use sabnzbd+ 0.6.6 en lottanzb 0.6 with Ubuntu 10.4

After installing sabnzbd and lotta no problems with downloading from usenet.
Bij mistake i closed the window of lotta while downloading.
By restart of lotta de lottawindow pops up but now my menu (add - pausse - clear- download) is inactive.

My config of sabnzbd is not changed i only cleared my downloadfiles.

somebody have a solution for this problem?

Thanks
