I recently re-installed my copy of Vegas Movie Studio HD Platinum 11.0, which is super-easy to use, and tried to export my project as an MP4 or other common video format and after three attempts with a variety of export formats, have yet to produce something that I can upload and others can watch. It's not yet ready for YouTube, so that's not an avenue I can use at the moment. Where can I find any patches or updates for this version, or is it so old I need to buy an upgrade? Would prefer to just keep using this for now, if possible. Thanks.
