PUN Multiplayer Errors at Importing

[Yago]

Hello!

I have created a brand new project Unity 2019.4.14f1.
After that I have installed:
Third Controller v.2.31 > Installed PUN 2 v.2.28.1 > PUN multiplayer Add on v.1.1.9*

After finishing importing the Pun multiplayer add on there is lots of errors and the Addon doesnt show up
in the Add ons Manager.

I have read the intructions and I believe I have all the versions up to the date,
what do I am missing here?
Any help would be really appreciated!!!
Please find attached a SS of the Log

Kindly

PUN was recently updated to version 2.28 and they had some API changes. Thank you for initially letting me know about this. I am releasing an update which fixes this now.
