I am having this problem everytime I try to run a decaying process

[Sihyun Jeon (shjeon)]

What does your log file say and how do you give commands to madgraph to provoke that error?

[Olivier Mattelaer (olivier-mattelaer)]

Actually I have to release 3.5.5 (likely next week) that fix that particular issue.
In the mean time please use the Long Term Stable version (2.9.19)

Cheers,

Olivier
