<div> </div>
<div>I haven't changed anything in NMM last 1 year and there was no any problem.</div>
<div>The only what was changed by computer - Linux Ubuntu upgrades.</div>
<div>After the last one a week ago WRF NMM stoped to run.</div>
<div> </div>
<div>Any help is highly appreciable! Maybe I need to reinstall WRF NMM with new parameters</div>
<div>in configure.wrf? Please help if you can.</div>
<div> </div>
<div>Kind regards,</div>
