Another reproducible crash: I wanted to listen to 'fluterror.sid', which is from 2011.
1) It is not in the list of SID tunes searchable in Modizer, because Modizer has an older version of the HVSC included. Update #55 was recently released, which include 40400 tunes. Modizer should update its list of searchable tunes.
2) So I took the route through the internet:
'Browse->Web', entered 'hvsc.de' in the browser text field, entered 'fluterror' in the HVSC search box, clicked on the single result and then on the download link. Back to 'Browse->Local browsing->Downloads->Fluterror.sid' and Modizer crashes.
