Toshiba Gigashot HD Camera & Imagemixer 3

Hi Guys
I;ve just bought Gigashot HD camera GSC-K80HE with bundled software imagemixer 3 & Nero start smart essentials.I've uploaded video & stills into IM3 library. I opened Muvee 6 auto producer (pre loaded on my pc) to try and make my first video. I tried to drag & drop images from IM3 into Muvee and failed. are these programs compatable. What I want to do is learn how to go about this task properly from the start, bearing in mind I'm new to this. can anybody advise how to use IM3 & ultimatley produce a decent video.
