Cannot connect to .mdf file (Lack of permissions)

Hey,

Just tried to create a new Data Source in VB 2010, apparently I don't have permission to connect to the 'Login.mdf' file I recently created in SQL 2008. Does anyone here have any knowledge of how to surpass this problem? I'm the Administrator of my PC and have full permissions and UAC is turned off so that shouldn't be the problem either.

Any help would be greatly appreciated...
Thanks,

Spec

Open the sql server and have a look at the owner and the permissions of the database.
