ProGet doesn't uninstall cleanly / No access on reinstall

I have installed the trial version of ProGet Enterprisse as IIS app and evaluated various things. I set up LDAP authentication and two feeds, and https-only access.

Some things didn't work out; IIS permission errors (500) when a developer / admin with rights to repo #2 but not to repo #1 tried to upload packages...etc.

So I uninstalled it.

Later, I thought I should give it a second try and re-installed it.

However, now I cannot login with Admin/Admin (as I did the first time), and so never get to actually set up the new install. In addition, the newly installed empty ProGet shows the two feeds that I had created before in the tab.

I would like to give it a second try, so how do I get ProGet to uninstall cleanly so I can login with Admin/Admin again?

As a precaution, uninstalling ProGet does not remove the ProGet database.

If you installed the bundled SQL Express instance, you can do this with:

osql -E -S .\PROGET

ALTER DATABASE ProGet SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

DROP DATABASE ProGet
GO

Thanks, this solved the problem!

I ran into similar problems myself with the latest version of ProGet as of 10/22/2013. It seems that the name of the DB has been changed to BuildMaster. I didn't see any ProGet database but there was one called BuildMaster so I followed the directions substituting "BuildMaster" instead of "ProGet" and it seems to have worked.
