If you send me your project in PM I might be able to save it.

Or you can follow this guide how you can do it yourself

My way of doing it Notepad++ Install xml plugin 7Zip (no need to rename aia to zip etc) Loading the project in MIT Check count of blocks for the affected screen Check count of <block in *.bky file [bild] Search for in this case for block 4977 (this is where the first issue starts and it might be more) ^(.*?<block ){4977}\K [bild] And as mention above [bild] And you are done.. Edited, Knowing that it is an extension that is missing then we can follow this
