As far as I can figure, it's the same error "type" and is probably being cause by the same issue. Try the following:
1) Copy all files to anoter location (If it's current in the administrator accounts documents as set by default by Visual Studio).
2) Open up [Microsoft
Website], download the Microsoft SQL Server Management Studio Express - Community Technology Preview (CTP) November 2005 program. Once installed, open it up. It may give you an error mentioning something about a volatile parent key. Ignore that and click continue. Right click on the database connection in the database viewer (Left Column, bottom/middle panel). Click ATTACH DATABASE. Browse to your database file to register it. [Just in case scenario.]
3) Confirm your connection strings pointing to your database file. Make sure they are pointing to the right database file. [
|DataDirectory|Database.mdf ] or whatever you named the database. The |....| needs to be there.
4) Copy your SiteUrls.config file from your /config/ directory to the root directory of your projet.
If you still get the error, I'll debug it for you. I fixed mine. =)
