Files missing on a Mac

I uploaded a folder with two videos taken of my workshops to Skydrive on my iMac. Then I sold the iMac and installed Skydrive on my MacBook Air. When I opened Skydrive on the MBA, the enclosing folder was there, but there were no movies in it. Nor were they on line. This is a big problem as I now have no way to upload the DVDs onto a MBA and am leaving for travel during which I was planning on editing and using those videos to show to prospective agents. What good is a cloud storage that loses your files! Microsoft, please tell me you have my files somewhere and can restore them.
