Template running well in PM but not in ZP?

[Davinci]

Hi,
I am a new user of Zennoposter.
I have created many templates and run well in PM but when I try to run them in ZP, several templates got error. In log message written http://postimg.org/image/vanz5rv7r/ and Instances window not appear unfortunately.
What is actually happening?

Error says that HTML element was not found on page.
You can try to add pause before interaction with this element.
