Dear MadGraph Team,
I encountered an error that I don't know how to resolve when I try to generate events from an imported model. This error only occured after I updated my MadGraph today.
When I try to generate said events I get the following error:

Hi,
Thanks a lot for the feedback and sorry for the trouble.
Could you attach the files:
1. /storage_
2. /storage_
Maybe one work-around to this bug would be to add the line
0.9 = second_
in the run_card but my guess is that this is just going to create a crash at the compilation time (if like I think, your file madgraph/
You can see here the changes that should have been done to that file:
https:/
I have checked the uiuc and the ucl server and the command requesting the change to that file are correct. I have also run the update function from 2.7.2 to 2.7.3 and I do not reproduce that error.
Maybe one solution independently of the above question is to install a clean version from this link: https:/
Thanks,
Olivier
