Can not Access an applications Database

Hi,

I use a program call loc as a workstation on my computer and I connect a central server which runs the SQL database. When I log into windows as the Local Admin I can use the program and access the database with no problems. However when I login with my own windows account I can not access the SQL Database. I have added my self as an administrator with no luck. The funny thing is that other people can log onto windows with their own account and access the database with no problems. Its just seems like my account with the problem. Please help!
