Problem with El Guapo´s Bam Bam Bigelow mod

[DoomMaster]

I can´t open the pac with x-packer (control+x)  to update arcs. I got message invalid pac file. How can i fix this? I´ve tried with both files, blue and classic mod. Any help would be apreciated. Thanks in advance.

Because he released the .pach file. Press ctrl+3 to open.
