Assertion in line

[Kilmo]

Hi guys,

I have been running ProTools 11 successfully for a few months now but went to open a new session the other day and was greeted with this:

Could not create a new document because Assertion in “/Volumes/Development/110287/AlturaPorts/DFW/MacBuild../Views/UMenu.MacOS.mm”, line 1357.

Can anybody help me out with what I need to do to fix this as I have no clue what that means and I have an important uni project I want to complete this weekend! Please explain in very simple terms if possible, I am new to this and am still learning my way around!

Thank you in advance.
