task not available in studio from project created with SDL live essential - also anonymous user in SDL Live Essential

when trying to open a file for translation in Studio - which was created with Live Essential - I receive a notification that there is no task available - there  may also or precisely an issue with the user to whom tasks are assigned: in Sdl live essential there is only an "anonymous user" . and. in live essential there is no possibility of changing users as there is no user tab under "resources"
