InfoPath Dev

I have a form library in sharepoint 2010 named Reviews, to which I have published a form template. If I go to the Reviews library and click "new document", it opens a blank form, and I can fill it out and submit it. It submits back to the same library. When I click on the item in the library that is the form I just submitted, I get an error:  This form cannot be opened in a Web browser. To open this form, use Microsoft InfoPath. I also have workflows that automatically create form in reviews that are partly filled out, but when I try to open these items, I get the same error. Why does this happen? How can I fix it? Thanks!

I've never seen this error, so I would imagine that it's a problem with your form, your workflow, your form library, etc.

I would try a brand new form, a simple browser form, that submits to the form library, and that's it. Does it open in the browser correctly when you reopen the submitted form?
