Lost Admin CP link !! to My vBulletin pages !

[cammot]

I first changed my home page on admin CP home page option to go to my CMPS home page, rather then the Forums page which it was set on. In doing this I achieved the intended results on my vBulletin site, but I have now lost the link to my vBulletin from my Admin CP pages. Where I originally had on the top right hand corner the link 'Forum Home Page'. When I click on this link instead of taking me to my vBulletin site it goes to a 'Not Found' 'The requested URL /.php was not found on this server'.

How do it correct this so that the link on the Admin CP takes me to my vBulletin site.

Thanks
