RW 7 upgrade problem

Hello, I just upgarded to RW 7. Previous version was 6.4. Here are some of the problems I have:

-I’m experiencing lots of crashes
-I have both RW 7 and previous version in Application folder. If I open RW7 and try to use the projects in older version
it dose not load, or in some cases you don’t see no content. I’m afraid I may loose lots of work done is RW6.4

  • Most addons from older version don’t work or behave strange- freeze, crash etc.

I have macOS Sierra 10.12.4
