Security Settings and Field Extraction

Question

Hello, I've run into a bit of a problem in .NET(C#) when trying to automate data extraction from a PDF. Specifically, I get an error stating "The document's security settings prohibit the operation being performed". The security method applied to the document is "No Security". However, the document restrictions summary says changing the document, document assembly and creation of template pages is not allowed. Below the restrictions is a paragraph that indicates that the document restricts some Acrobat features to allow for extended features in Adobe Reader. It says that I may create a copy of the document that is not restricted by using File > Save a Copy. Using the copy, I'm able to extract the data that I need.
Is there a way that I can go about removing the restrictions from the document, either on the creation side, which is done manually, or on the programming side? I haven't found a way to duplicate the "Save a Copy" functionality with AcroAppClass.Save(). Exporting data is also disabled b/c of the restrictions. I noticed that I can extract pages manually and save them to a new document, which gets rid of the restrictions, but I couldn't find a way to do that via the PIAs.
Any help or advice is appreciated.

Ahh, I overlooked GetType(). Thanks.
Calling the saveAs method works fine when just passing one parameter (a file name to save to), but when trying to pass multiple parameters I get an internal exception. I may be passing the parameters wrong, but I'm not sure.
For example:
object[] arguments = new object[] { @"c:\call\test.pdf"};
mJSObject.GetType().InvokeMember("saveAs", BindingFlags.InvokeMethod, null, mJSObject, arguments);
The documentation says there are 5 parameters:
cPath, cConvID, cFS, bCopy, bPromptToOverwrite
I tried using:
object[] arguments = new object[] { @"c:\call\test.pdf", Missing.Value, Missing.Value, true, Missing.Value" };
and this:
object[] arguments = new object[] { @"c:\call\test.pdf", "com.adobe.acrobat.jpeg" };
Unfortunately, I get "Exception has been thrown by the target of an invocation" when attempting to save using either of the above two methods.
