FXCM changed Margins

Hi,
I run my strategy on FXCM real-account. Everything was perfect until FXCM changed the margins this weekend.
I calculate the ordered lots how advised in the manual: Margin/MarginCost, f.i. 100 / MarginCost.
Since monday I receive the message "Balance over limit".
Yesterday I restarted Zorro - no effect.
What can I do?
Thanks for any suggestions.
Hans

It means that you need to withdraw money. Otherwise the account balance is higher than the balance limit of the free Zorro version.
