Hi Matthew,
Need to know what version of .NET and CR you are using?
You are likely correct, If CR can't find or doesn't have access to the data it will auto map the fields and delete what it can't match. In this case none match because it can't connect.
Could be platform also, 32 or 64 bit app and AppPool, what is IIS running under?
How you connect to get data into your dataset CR doesn't care so it is likely somewhere between the DataSet and CR the access is being denied. Could be CR Driver or possibly the WEB.Config file.
Make sure the app is loading the correct WEB.Config file from your app folder and not the default one that sometimes happens.
Process Monitor can help debug where everything is being loaded from also. Could even be that you are not deploying the correct CR runtime MSI, we don't support simply copying over the runtime, must be installed using the MSI or Merge Modules.
Searching this forum has a lot of info also on how to.

Oh and I see you had this post also: http://scn.sap.com/thread/3157366
Answers the version question.
How did those suggestions go?

Found it. It was one of those field mismatch types. Found it using the method suggested here: http://scn.sap.com/thread/1232494.
Thanks so much for the help!
