Anybody else have this kind of problem:

After updating to MissionPlanner 1.2.55, the entire MissionPlanner crashes during its start-up.  The splash screen shows up and very soon after that it stops responding.  The console shows a "fatal app exception":

Steps to reproduce:

1. A clean install of MissionPlanner 1.2.53

2. upon start-up Mission planner informs about an available update.  Accept the update.

3. When update is complete, updated MissionPlanner launches and exhibits the problem described above.

Workaround:

Uninstall MissionPlanner and do a new clean install of 1.2.53.  Do NOT accept updates!
