Comments overloaded?

Hi guys, ??

Over a period of about a month, with no proper spam-filter on my comments, I’ve amassed 1,600 comments, 99.999% of which will be spam, although I know some friends have left comments that haven’t been posted.

When I click the ‘comments’ section in the back-end it takes me to a blank page and doesn’t load them – I’ve now tried this on many browsers, Mac & PC based and nothing works.

Is there any way to fix this and if not, can I just delete them all and start again? (the latest comments that is, not all the already published comments or my posts)
