I am a paid user for eM client 6, I found I can’t re-establish my gmail account after I changed my password. It keep popup an error message after enter the new password saying that system detected my JavaScript is disabled on my browser. This is annoying and I can’t use eM client any longer.
First, Make sure that you are on the latest version 6. The earlier ones did not support 0Auth2. The latest version is 6.0.6.0.24985.0 and is available http://emclient.com/release-history.
