BaseCamp keeps crashing

BaseCamp keeps crashing when I try to amend a route - 'application has stopped working'.

Initially 4.5.1 so installed 4.5.2 which wanted .NET Framework 4.6 installing. Did that but still crashing.
Uninstalled BaseCamp and reinstalled - still crashing.

Used windows restore to go back, including 4.5.1 - still crashing!

Windows 8.1 fully updated. MapSource still working.

Any suggestions please?
