It took me 5 clean manual installations on Godaddy to find out when I define new fields in the profile, with the first Admin profile update whole the login for all users takes you to "An error has occured" error page with a url that says "Input string was not in correct format " and whole the portal dies. I guess the problem is sending and storing the new field in the data base. I don't have enough technical knowledge to find the remedy. I tried logging with host account and remove the profile or even whole the users and define a new admin and whatever I knew, including manipulation of aspnet tables but it never worked.

Now my questions:
1- Is there something I am missing? Is godaddy to blame for the problem?
2- When it happens, is there anyway back tokeep the SQL database and not install everything from 0?
3- Is there the same problem with the 4.3 new release?
