After several (less the 50) starts of an application there is impossible to start one.

Reason (as I guess): Impossible to get several java files from Dukascopy server.
After error accepted once there no possible to open application again.
I checked in with java 6 and java 7, Windows XP SP2 and Windows 7 64Bit, different internet connections (include DC's one) and there no affect on the behavior. After restart of the computer the error persists.

The following error exaample is received:
Error: https://www.dukascopy.com/client/demo/j ... 2.6.63.jar

Hi egilbaum:

Clear java cache and start the plataform with last jnlp if you are using a downloaded before jnlp.

I hope that helps

Best regards

Trade well and good luck

JL
