SQL Server CE v4 Bin Deployment

Question

I'm trying to create a VERY simple test web application to get SQL CE4 and bin deployment nailed. It is proving difficult. I've read and I beieve followed all the various pieces of advice and guidelines Google could throw my way. Still no joy :-(
So I've got one ASP.Net web application (the default created by the VS2010 template) with a SQL CE4 database added to the App_Data folder. It has one table with two fields (identity and string). A data grid has been dropped on the About page and
connected to the database using a SQLDataSource. This shows the data ok. I run the webpage using the VS2010 IIS on my development PC and it works ok.
I follow the instructions for a bin deploy and copy the website to my test server (Windows Server 2008 R2 running IIS7). Access to the database is denied. My test server has a number of different websites deployed to it using various technologies; Silverlight,
ASP.Net, MVC3 (bin deployed) and they all work fine. I have set up this website just as I would any other.
I'm tired after a day of reading and banging my head on the table and going out for a beer! Perhaps I'll have a moment of clarity at the bar...
In the meantime,  can anybody quickly build and deploy a similarly simple test web app just to confirm it's me in error and not the world please?
My development ecodustbin is Windows 7 Pro (64 bit) / VS2010 / Expression Studio all patched up to date including the Windows 7 SP1 which I applied first thing this morning (not a quick job). As I said the test server is just Windows Server Standard 2008
R2 with IIS7 (and also SQL Server 2008 R2).
I did try deploying to my external shared hosting platform just in case it was my test server configuration at fault, and the test application failed to work from there either.
Hopefully and probably this is just me not ticking a box or selecting something from a dropdown somewhere in VS2010 and when I sit down again tomorrow the answer will hit me like a wet fish. Here's hoping.
In the meantime, any comprehensive, clear, idiot-friendly instructions based on an actual working example would be great!
Cheers,
Glyn.

Hi Erik,
A new day, a new test app. As above, one ASP.Net web application by VS2010 template, one simple CE4 Db with one table with two fields (identity, string). One datagrid on the About page connected using SQLDataSource.
SQL CE dlls copied as instructed by your link above. Web.config changed as instructed in that link, but with System.Data.SqlServerCe version entry changed to 4.0.0.0 instead of v4.0.0.1.
Works fine on development machine, but when copied to server it results in this error message:
==============================================================
Access to the database file is not allowed. [ 1884,File name = D:\inetpub\CE4_03\App_Data\MyDb.sdf,SeCreateFile ]

So I'm back where I was yesterday! :-(
Any ideas? Have you tried reproducing the above very simple test application using all the current tools? I notice a lot of the articles are from last summer when people were testing using the CTP. I wonder whether something subtle has changed in the meantime?
Or maybe I'm just not doing something in VS2010 which is so obvious nobody mentions it?
Thanks for your thoughts,
Glyn.
