finally I started successfully the Mt4 for a back-test, but before Tickstory started not the MT4 directly but but Birt's TickDataSuite.
I had to move the tds.exe out of the expert folder, then Tickstory started the Mt4.
May be there is a way to have you both installed without inter-fearing each other?
I know it's more a cosmetic issue..
And now I found another, a little bit nasty problem. All my tick data are on an extern usb-hd and from there Tickstory created the history files for the optimization. The mt4 was started by Tickstory and is actually running an optimization that will probaly run until tomorrow. Now I want to close (shut) down that usb-hd but Windows tells me, that a program is still using or accessing the usb-hd. Is that Tickstory? I shut down Tickstory, only the mt4 which was started by Tickstory is running. Could it be that some flags weren't changed? It would be nic if you can find a solution. For this time I will just switch off the power

Thanks a lot for this great program!!
