Fatal error occurred

Thank you for crating a great plugin. I started to try it and figuring out how it works.
I just updated your plugin then suddenly my wordpress dashboard (wp-admin) cannot be access.
What I all can see is this message below
It look like something is not right on “line 1062”.
Please kindly and urgently fix this error.. otherwise I cannot upload my content which is a quite big problem.
