There are several unlicensed versions of the program. Try this one, which is indeed free. Though this 'lite' version has some limitations, you should be able to export in one of several YouTube formats. Use their uploader if necessary, after exporting as an Mp4 or AVI video file.
(The version that you now have loaded may present the option to use the 'lite' edition if you attempt a standard Windows uninstall, under Control Panel|PROGRAMS AND FEATURES.)
That accomplished, and with the completed project on the timeline, use FILE|SAVE AS PORTABLE PROJECT. When the .vpj file in the resultant, numbered folder is clicked the project will reload. That folder contains ALL the source files.
The vpj is just a control file. FILE|SAVE PROJECT AS often, giving it a unique name or number so earlier saves won't be overwritten. If you move the source files, the vpj won't be able to find them and will ask you to resolve (locate) them. Once that's done do another SAVE PROJECT AS. This creates a vpj that points to the new file locations.
In any case, someone will review your project if you upload and share it, and they may be able to create an export that matches your preview. This isn't difficult.

If it contains sensitive material you can link it in a personal message (PM) to me, via the envelope above. Be sure to FILE|SAVE PORTABLE PROJECT AS, not simply SAVE PROJECT, and don't forget to share it.
