Ok, I've solved it!!. I install the software again (the third time I reinstall this week) and seems to be solved.
I don't know what happened beause I have no scripts installed and I have the last Mac OSX in my computer.
I have reported some bugs to Anime Studio support but they had never answered me (instead of this they send me thousands of advertising to my email). SmithMicro support seems very bad to me. I'm not happy with them

.
I was buying Anime Studio from 6 version and the only answers I get to my problems is here in the forum and with videos in youtube like yours.
Thanks for your reply Victor.
