Problem With SQL Server Web Data Administrator

I'm so sorry if this is a stupid question. I'm experienced PHP/MySQL developer, but this is my first SQL Server project, I'm really not familiar with Microsoft development tools at all. I have Visual Studio .NET installed. I've just downloaded and installed SQL Server Web Data Administrator. There was no errors during the installation, but when I'm trying to use it to connect to the database I had set up on the hosting server, I get the error message below:


Server Error in '/webadmin' Application.

If anyone knows what is the problem and can point me in the right direction, I'd really appreciate.
