aMCatNLOError : Some tests failed, run cannot continue

Hi,

I've been generating, decaying and showering the process p p > W- + bb [QCD] and I am now getting an error right at the beginning:

Error detected in "launch "
write debug file /unix/atlas2/ines/software/MG5_aMC_v2_1_0/Wmbb_100TeV/run_55_tag_1_debug.log

aMCatNLOError : Some tests failed, run cannot continue.
 Please check that widths of final state particles (e.g. top) have been set to 0 in the param_card.dat.

The contents of the run_55_tag_1_debug.log file are:

What is surprising is that I've generated a fair amount of events already, in several different runs, and only now this crash occurred. I am therefore hesitant to change anything on the parameter card. Any idea of what could be going wrong?

Thanks a lot in advance!
