Sorry that didn't work I set it to 50,000. All I'm getting on the crawling page is:
No sitemaps found
Sitemap was not generated yet, please go to Crawling page to start crawler manually or to setup a cron job.
Run in background
Do not interrupt the script even after closing the browser window until the crawling is complete
No start button. Seems as if, when i interrupted it, its gone now?
