Blocs keeps crashing 3.4.6

Hi, I upgraded to the newest version but now as soon as I open a older porject it crashes straight away. If I start a new project it lasts about 2 mins before crashing. Deleted Blocs and downloaded a new on from the Blocs webite but still the same problem. Downloaded the Bloc beta but again it crashes. Is it just me?
