Are you able to open the Web Site Administration Tool, available from the Website…ASP.NET Configuration menu?  Once you have opened the tool verify that it contains an "Administrators" role.

I can remember running the asp.net configuration setup tool multiple times both from the command line and the GUI.  So maybe re-running the tool will help.

From looking at the error message it seems like the stored procedure is expecting the aspnet_CheckSchemaVersion to have been created by user dbo.  Your stored procedures might have been created by your personal crystaltech database username.  So my observation is that you are running into a similar "dbo" problem.  Maybe there is someway to make the dbo user the owner of the stored procedure.  Like I said before, I am a new to this and I don't have all the answers.  But hopefully I have been some help.

Note that if you create a user in the Web Site Administration Tool that they will not show up on the membership page.  See http://forums.asp.net/1155458/ShowPost.aspx. 

Here are some other problems that I have run into once I got my site up and running.
