InfoPath Dev

For quite some time, when I was emailed an InfoPath Form, it came to my email as it should; when I opened the email, the form would automatically open and I could edit it. Now, I cannot open it as a "form" and now there is an attachment, which is the form! What is wrong???

Hi, can you check on your form option and check Email attachment if you don't want to send it like an attachment, uncheck the box.

Found the issue. Had to do with Enabling the InfoPath form in Outlook. I don't understand how that would have changed by itself. Oh, well, at least it is fixed now. Thanks!
