Hi Sven,

I usually can run the GSA Email Verifier without any problem but since 2 days ago, My GSA Email Verifier keep freezing, i import the 15K email list and then use 100 private proxy to verify the email.

Here is the screenshot : http://i.gyazo.com/90191a0beeb4a57d595524ef69218a1f.png

I can't see anything, it become white screen or black screen..

Please advice me how to fix this?
