Gutmann Mega Macs 55 after the launch he wants to perform an update

Hello together, I have the following problem: Version: H2.2 Year of construction 2003 Ser 303xx Megamacs 55, bootes, starts update, and stops there because there is no connection. In the past there were error messages already error 033007. Various .BIM files could not be found. From other reports here this seems to be related to an update attempt. Does anyone have a solution for the problem here? Is there a dealer you can contact? Gutmann himself can not help Since it is no longer in support. Thank you and greetings, Marco.
