Having some issues with DNS records;

I'm trying to host my personal domain using mobile me, Ive made the instructed DNS record changes ie

www cname web.me.com.

and deleted the other records except MX as I need to use 123-reg mail forwarding.
Works ok if typing _http://www.mydomain.co.uk_, problem is if I type mydomain.co.uk into a browser I get a 123-reg holding page

have tried;

adding - * cname web.me.com. - doesn't work

put the @ record to 123-reg IP back and used their web forwarding as instructed by 123-reg support - this ends up with an error saying dns will not complete, presumably as it adds a second www record.

I am at a loss to know what to try next and am now at monkey typewriter stage
