My colleague is trying to upgrade freelance2000 from 6.1 to 9.2 firmware on Win XP, he succeeded to upgrade, but the system did not work well in redundancy option, alert message telling that the redundancy communication module needs to be upgraded also to new version 9.2. When he tried to upgrade, he couldn't find the original project file which to be imported in the project tree,, how to solve this issue,,!!? or if possible to provide us with the project file,,!!?
