Problem with Roo security, error connecting

I am a new user of Roo.
I have a problem connecting when starting Roo. I am using an Apple iMac Book Pro that I bought in 2010.
I have been using Roo, was using it for a while and worked fine.
Then, when I started Roo it started giving me a security error that I can not undertand. I am enclosing the error log in a zipped file called roo-error-log.txt.zip.

Any answers will be deeply appreciated. I like Roo a lot, since it promises to save the developers a lot of time in coding.
