I would like desperately to download trial versions of Photoshop Elements 10 and Premiere Elements10

I purchased this combo for my mac and am now moving to a macbook air which has no dvd/cd drive. The remote drive access doesn't seem to be compatible with the adobe installer and the known issues with elements' installer isn't helping either. I have my box and keys, but I can't get the installs to work remotely or by making dmg files and dragging the disc contents. Please help! thanks.
