New to Everything. Can't import AVI ?

SnowTiger Posts: 1 Just Starting Out

I just purchased a starter version of HitFilm Express hoping to edit some video created from my Nikon Camera which is in AVI format.

It appears AVI is NOT Compatible with this software.

I know nothing of Codecs etc and therefore have no idea what to do OR if there is anything I can do. Will I be able to import my video or not and "if not" can I get a Refund because the software will be useless to me ?
