the generator stops crawling after a minute or so and shows my site's 404 page in a frame below the 'Please wait. Sitemap generation in progress...' message.

It also won't resume and get past the number of pages it's indexed at that point, for eg:
Pages crawled: 153 (88 added in sitemap), Queued: 177, Depth level: 2

I've used your generator for this site before, and it worked fine, but I've just upgraded and wonder whether there's something else I need to configure?

Thanks for any help.

it looks like your server configuration doesn't allow to run the script long enough to create full sitemap. Please try to increase memory_limit and max_execution_time settings in php configuration at your host (php.ini file) or contact hosting support regarding this.
