I have localized EVE Online client and cannot import my personal and corporate orders from files.

By default EVE Online saves orders in files like “My orders-2011.06.15 1810.txt”. But the localized client uses translated file names. For instance, in German it will be “Meine Aufträge-2011.08.16 1356.txt”.

To fix it you have to open import preferences (Preferences, Import tab) and specify correct patterns for character and corporate orders. For instance, “Meine Aufträge-*.txt” for character orders.
