"web.config cannot be changed" when trying to enable ORM for a project.

I've downloaded the latest edition of Open Access and I cannot use it on an existing website.

When I try "enable project to use ORM", everything is fine on the first screen.  I click next and on the "Does your project contain the following?", persistent classes? is greyed out and not selectable, however DAL is selectable.  If I select DAL on the next screen everything is greyed out.  The "Select connection" dropdown is defaulted to "none".  If I select "custom defined", then the other boxes become selectable.  I click NEXT and on the finish screen, I get this error:

"OpenAccess Error"

"The following problem(s) have occurred:

1.  Config file:  C:\websites\sitename\Web.config cannot be changed.  Cause:  System.InvalidCastException:   Unable to cast object of type 'System.Xml.XmlComment' to type 'System.Xml.XmlElement'. at Telerik.OpenAccess.Sdk.Addin.Xml.XmlHelper.GetXmlElementByAttrKey(XmlNode parentNode, String elementName, String attrKey, String attrValue, Boolean partialMatch, Boolean create, Boolean prepend) at Telerik.OpenAccess.Sdk.Addin.Core.ProjectEnabler.UpdateConfigFile(VAProject project, Parameters parms, String configFileName)
To fix the problem(s), try the following:

Re-execute the 'Enable Project" wizard on the project or execute 'Check Settings' from the OpenAccess menu"

When I re-execute, I get the same error.  When I check settings, the only thing selectable on this project is, Validators and Update assembly references and they are selected by default.  If I click "Check", everything is fine there.  There are no errors and I still can't enable this project.

Help!

I removed all of the comments from my web.config and this time it ended without errors.  However, it's still acting flaky.  When I try to reverse map an existing database, it's now saying it can't find my connectionstring in my web.config.  I'm looking right at the connectionstring.
