German symbols in QCHarts

[hhhc]

Hello,

I have a problem loading German stock symbols.
Although I have subscribed to "Deutsche Boerse: Spot Market Germany (Frankfurt/Xetra)" I still don´t get to see German symbols like e.g. ADS-XET.
Is the stock symbol format correct? At least that´s what the symbol lookup database released.

Please help.
