Help! MQL5 must be repaired: New Order button is deactivated: "investor mode"

My manager has blocked my account, because I couldn`t put more money in it! Now the New Order button is deaktivated and I can`nt do any tradings!

Please help: how can I use the platform again? How can I activate this botton? My account now is now "investor mode" - Trades are not allowed! - Made it by my accountmanager without my permission! 

MFG.: K. Gabor
