Sync will not work- very frustrated

Bruce

I upgraded the program on my PC to 3.0.115 on May 15th, 2015. I am unable to sync with my android running the app downloaded from Google. When I enter the sync code from my PC into my android the screen freezes on my android. The only option I have is to change all the passwords for sites I use on my android to a new password I can easily remember. This is more than frustrating. When, and if, I get them synced again I will never do another upgrade. It seems every time I upgrade I run into problems. The other option is to switch to another app- does anyone have a suggestion?
