Thank you for the info. Indeed when I click Trade button straight away it seems that the prices are downloaded but at the end I get Error 055 anyway:

When I open the .t6 history file in ZHistoryEditor, the data's there, with daily resolution, going back to 2005 or so. I tried deleting all the history files and downloading them again but nothing changed. I also tried to comment out all the assets in AssetsZ8 except one but I'm still getting the same error. I've read the manual but still the Error 055 is confusing for me in this context.
