Problem submitting a new solution

Hi everyone.
Is anybody having troubles submitting a new solution?

I'm trying to upload a new solution because my first solution was a test, but I get this message when I do it:

1 error has occurred
There was an error while uploading your solution.

Someone have submitted more than one solution?
I'm at a Starbucks, maybe some port is blocked...?

Thanks.

Hi,

If you still have problems, you can email to antonio.h.hernandez@oracle.com, he will help you to upload your solution.

Regards!
