Unable to configure HCP Mobile Services - Error at accessing HCPms Service

Hi everyone! I've been asked in my job to configure the HCP Mobile Services but I can't manage to get it working!

I followed the documentation to configure HCPms (SAP HANA Cloud Platform Mobile Services), the service is "Enabled".

The errors that come up are:

1. When trying to subscribe to HTML5 Application "hanamobileprod" and trying to save it says: "Subscription or Application with name mobile already exists. Names must be unique across HTML5 applications and HTML5 subscriptions."
   If I type any other subscription name, let's say "othermobile", it appears to be working, but it's not listed in the table and it still says "Subscribed HTML5 Applications (All: 1)".
2. Can't subscribe the account to the mobilejava JAVA application because there's not any option to subscribe any JAVA application.

Maybe those 2 points are no longer necessary to make HCPms work, because I've created a trial account and couldn't make those 2 points, but the HCPms Service can be accessed anyway and it works well.

When I try to enter the HCPms Service in my "productive" HCP account, I get the next error:

"HTTP Status 500 - An internal application error occured. Request: [reqnumber] [account]:mobile"

[reqnumber] is a number like 375289375

[account] is the account name like a01b00001

And it does that when I try to access any other HTML5 application, like the webide app, that is Subscribed (the only app list as subscribed).

Can you help me to get this to work? Any ideas you could give me is really appreciated.

Thanks in advance.
