Errors Persist In New Database(s)

I am getting this error condition on two different machines, so I think it is something I am leaving out.

The database is being created with a script (pasted at end of this post) executed within SQL Management Express 2005. The database shows up in the database tree but is not expandable, i.e. no plus sign. If I try to get Properties, the following sequence:


Database cannot be opened due to inaccessible files or insufficient memory or disk space Error 945

TITLE: Microsoft SQL Server Management Studio Express
------------------------------

Cannot show requested dialog.

ADDITIONAL INFORMATION:

Database 'Cart1' cannot be opened due to inaccessible files or insufficient memory or disk space.  See the SQL Server errorlog for details. (Microsoft SQL Server, Error: 945)

==============================================



I had been using "Cart" as the name, saw a reference that said not to use the same name in a new database. The new name is "Cart1"; no help.

In the application,  I initially get the "cannot find the physical file, but if I Refresh the page, I get: "Cannot open database "Cart1" requested by the login. The login failed. Login failed for user 'GW20Bob'

Please assist in this. I will test or answer any questions I haven't supplied.
