0 byte file size, Sky Drive corrupted my files, please help!!!

After moving moving to another computer and enabling my SkyDrive on windows 8.1, I can see the sync okay but the synced file sizes are '0 bytes'. No data in the files. Images cannot be open, text files are blank once opened. 

The files are there but just empty files, now i had very important data in my SkyDrive, i guess thats the concept to safekeep the files. I do hope that there is some way that my files can be repaired or retrieved back and Microsoft keeps a version of SkyDrive files (like dropbox)

Please help. Either it is some settings problem? or some thingelse, but one thing is for sure, files are just empty either i open the Synced folder or i open the SkyDrive on web, i even downloaded a fresh copy of a text file from SkyDrive online via browser but again it was empty.

Any help is greatly appreciated

Thanks
