I can not load my files in iCloud

when I access the page Numbers in iCloud I can see my spreadsheets, but when I try to open any of these files a signal indicating that is loading the file but does not stop to show the file, it gets the message loading screen. ..

I can not access to my files.

I try to access to my files with Google Chrome Versión 41.0.2272.118 (64-bit) and with this web explorer it is impossible to access my files.

If I try to access with safari now I can load my files.
