Question : SQL Server New Database/Premissions error

A new Test database has just been create and I have the exact same permissions that I have on the live database - However I can do anything with the new DB not even simple select statments.
I get the following error
"An unexpected error happened during this operation [MS Design Tools] - You may not have  permission to perform this operation, or the object tblclass might no longer exist iin the database"
Other people can access the test DB? Any idea wha the problem might be?

Answer : SQL Server New Database/Premissions error

Double check that your connection to the new db is really using your login that has permissions.
example: you have set up a sql server login with permissions, but your connection is using your windows login info.
