Sometimes there's an error while importing and I have to start it over again. only then it only uses the same results again (without even downloading) and I had to delete the title and add it again to get it to work.
I don't know if there's a setting or something for this, but I couldn't find it.
Thanks for your quick reply. I find out the trick after read your reply. There are several scripts cannnot be installed if the locale is Chinese (file label syntax error), so I installed the program under English locale and updated all my movies. After that, I changed the locale back to Chinese and the import function did not work anymore. Now I uninstalled and reinstalled it under Chinese locale (I just ignored all the error scripts.) and the import function works now.
So seems these scripts with file label syntax error caused the crash.
