Number of Webinar Practice Sessions?

Is there a limit to the number of webinar practices we get?

AND

Unfortunately, I pressed pause on recording at the beginning of my webinar session as people were coming in to my webinar, got distracted and neglected to press record.

Is it possible to retrieve a webinar is it hasn't been recorded?

Likely there's an obvious NO answer, but I'm holding out hope for another solution, rather than recording it again.
