Currently, I am trying to set up a Z2 test on a demo account with a broker that uses other names for the indices, e.g. I assume that FTSE100 in this broker's portfolio is UK100 in Z2, DAX30 is GER30 and so on. Can I just change the names in the file Data/Z12.fac or does that mess up things?

That will mess up things. Instead you need to add the name conversion to the assetFix function in the Zorro.mq4 script. Example:

Thanks, I'll try that ....

I changed the Zorro.mq4 script as you suggested. NAS100 seems to be called NQ100 with the broker I am using, and I also put this conversion into the EA script.

When I click "Trade", Zorro starts collecting the initial data, until it says "Error 053: NAS100 prices unavailable" (nothing about the other assets, though). After that, the program hangs for quite a while (no progress bar, Windows grays out the window), until the last message appears: "Read Z12.fac Z12.par ........................" and the program seems to crash (Windows keeps showing the "blue donut" cursor and the window remains completely unresponsive).

Do I have to enter the changed asset names somewhere else so Zorro can find them on startup?

Okay, I just found the solution myself. I just had not read correctly: NAS100 is not called NQ100 with my broker, but [NQ100]. I have included the brackets now and everything seems to work.
