Difficulty Importing Theme (MyBB)

[AceInfinity]

You aren't uploading from your ftp? Upload from an ftp client instead. Every webmaster should have one. Then you're going to have to point your admincp to your forum logo manually and also point it to where your images are if you uploaded all the images into a seperate folder. You'd create a new template, and point it to the directory of your images.

also, click on "ignore version compatibility". that helps sometimes too, if your theme was created in an earlier version. Assuming you have the latest version, because you should.
