I'm sorry for my lack of information in the first post. I'm running Windows 8. I am also able to run CloudExport and CloudPut. They do not give error messages. There was no other information given about Error Code 1000, see below:

I have not used my wolfram ID to sign up for anything cloud related.

Hi--

I just checked and I had no problem saving a file to the cloud and opening it up from the cloud. I'm using OS X 10.9.4.

I had previously signed up for various betas for Mathematica On-line, etc. so there may be a set -up issue. I was able to open a file I had saved with the on-line beta some months ago.

I would make sure that your Wolfram ID is being used to set up the cloud, and perhaps sign up for the beta for Mathematica on-line. (I don't know how to do that right now -- it may be by invitation only.) A call to supper (or sales) might help.

The good news is that the functionality seems to be working fine. The only problem seems to be set up.
