hello, My 1password used in win7, recently, I found that my 1password in windows cannot sync with my mac 1password. it says there is an problem with 1password helper. I follow the steps in the website , I reinstall the chrome extention, but I find I cannot use the chrome extention now. that is it said the master password in incorrect. and it still cannot sync with the server again. I think maybe I use the symantec antivirus software? but about 1 months ago, I can use this correctly. I hope someone can solve this problem for me. thanks a lot!
