Error message after logging in

I have not logged into my wordpress in over an year but the last time I did, everything was working fine and I did not make any changes. I tried logging in and I got this error message.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /home/bouncyj/public_html/x/wp-admin/menu.php on line 265

Please tell me how to fix this? My website is http://bouncy-bubbles.net

I don’t have any backups as I was completely away from the world of web-designing and ignored to make backups but I would still like to be able to login as my whole website is managed on wp. I don’t want to lose my blog and content. Any help will be appreciated.

Thanks.
