Files containing hyperlinks getting corrupted!

Hi, I had several Word docs in which I was compiling copious references with their URL sources for later use, and these have become corrupted. The only way I was able to open them was to use Recovery which gave me a mass of plain text - totally ruined my document, and now I have hours of work if I'm ever to restore these sources. This is only happening with files on Skydrive which have large numbers of hyperlinks in them. Is there any fix for this, otherwise I'm very regretfully going to have to find another option for file sharing.
