Hi Olivier,

Perhaps I wasn’t giving enough details.

I initially have madgraph 2.2.3 installed a year ago. Then, recently I realized that there’s an upgrade, so I removed it and installed madgraph 2.3.3. 
The error I reported happened when I try to use madgraph 2.3.3. I am wondering if I am not doing the upgrade properly. 
Now, I have switched back to madgraph 2.2.3 and things are working. And I am happy with madgraph 2.2.3 at the moment, so there is no rush to get to 2.3.3. Still it will be nice to know if I have made any mistake.
Please let me know if this rings a bell, or if there’s anything else I can provide to help understand the problem.

Thanks&Regards,
Vincent
