Zennoposter Code creator email verification Help

I'm still on zennoposter 3 as i think MP is little advanced to me.I was trying to make a pinterest account maker but the problem is i need to emulate click so i go for code creator which i used first time.I have successfully able to emulate click and all things work nice but the problem is i can't extract the invite link from my email.This was working on project maker before.I simply made some change in default regex so that it works on code creator(do i need to change any thing in code that is given by regular expression builder?).After all this when i try to debug to test if mail verification works i get error saying
What i'm doing wrong is it mistake with my regular expression or what.
My simple regular expression as on project make that works fine.
What should be i'm using in code creator?Help me guys.
