SQL Server 2005 error after update to windows 10

I have a SQL Server 2005 database that I can see in SQL Server Management Studio Express. There is a front end application, but since the upgrade to Windows 10, I cannot access the database with it. In SQL Server Management Studio Express there are no object folders listed for the database - and the summary shows 0 items. The database folder has a correctly named mdf file of 197MB. I have very little experience of SQL Server so would appreciate any pointers.
