the signal is temporarily disabled for new subsrciptions

 
I subscribed with a demo account with no problems but when i try with my real account it shows me  the signal is temporarily disabled for new subscriptions )
is that because of my low Capital
 

It can be for any reason, and all those reasons are related to the signal itself.
Besides (from the rules): "signals based on real accounts are available only by paid Subscription; signals based on demo accounts can be received only by free Subscription."
