I used to be able to import WebM files into Windows Movie Maker. Now I can't! I need to fix this as I am not going to pay money for a better screen recorder/an online converter service. Please help!

Also, Microsoft employees, I am fully aware that Windows Movie Maker lacks support for this file type. That is why I am asking this question.

And for the record, I am sick of Microsoft Employees answering people's questions with the problems they seem to be having. Thank you.
