I was at ver 4.6. 2  and upgraded to 5.0.01 ..  Ok, that was a mistake, so I re-installed my backup to ver. 4. 6    The site won't run.  I ran the install.aspx  and it says it's installed correctly and that my assembly version is 4.6.02 and my database version is 5.0.01.   I suspect that's a problem ?     I 'thought' the service provider keeps backups, but apprently not on MS2005 and if they did, it's too late to restore it now. (I did do a remote backup and download using some freebie s/w, but I haven't tried to import it)    Did 5.0.01  do something to the database ?  And is there a way I can un-do it?  Start over ?    Thanks

 Ok, that's what I was thinking, so this morning I upgraded my insallation back to 5.0.01.  When I triggered the install, the page went blank and stayed that way.  After four or five minutes, I went to the web page and the first page was there but I couldn't sign in.  Searching thru the previous qeustions/answeres seemed to indicate I wasn't connecting to the database and I indeed found a typo in my DB user ID in the web.config.  I corrected that and triggered the install and got an error message that the database connection string can't conect to the database named.    I went to my ISP and logged in anc checked the database connections .  I see this listed :    (@setUID) select * from users where uid = @set UID     There seems to be another connection (didn't write it down) that's also sleeping.  There is a warning that if I delete these connections I might lose all my data.     As an engineer, I tend to push the buttons to see what happens.  That's how I got into this mess so I'm getting a little reluctiant  to do much more. Any suggestions ???

It may be that the encryption keys used for the passwords changed when you switched web.configs.  I would suggest registering a new user, and then copying that user's password information on top of the host user.  Then you can use that password, login, and then change the host & admin passwords to a known value.

The passwords are stored in the aspnet_Membership table.  You can look up the username in the aspnet_Users table, and then use the UserID to find the same record in the _Membership table.  Make sure you update both the Password and PasswordSalt columns.

Hope that helps,
