I have a zorro S subscription and have run into a problem with downloading data from Yahoo. I consistently get error 056 for instance using the Z8 algorithm in test mode. It has worked in the past. I reinstalled zorro, but without success. The problem started after I deleted .t6 files of some assets, but I don't see how this would affect a new installation of zorro in a new directory.

Thank you for that reference to a previous thread.

Unfortunately, this means that testing of Z-systems will no longer be possible until a new version of zorro is released, since it seems not possible to run older Z system versions with a beta version. It yields the error "compiled with older version". Or is there a work around?

Any possibility of modifying zorro 1.54 so it works again with YAHOO?

You can download the data with the beta version, using the assetHistory function. Then copy them over to History folder of the release version and start up Z8.
