Sequenced videos and software issues

Hair and skin ( no transition, bit quick, needs one) 

Eye, lips and nosehair ( managed to get three together!) film dissolve transitions more subtle than cross dissolve.

Undertongue and eye: no transition, needs one)

Having big problems with Premiere essentials software. It keeps crashing. I have freed up more memory and defragged the hard drive however it still crashes. I've managed to make three new videos of two sequences each. I want to vary the images and have them possibly repeating and chasing each other through the three projections. Going to be harder than I thought. Timing and stuff.
