DuIK - "Unable to execute script at line 319. p is undefined"

Hello, I'm having trouble with this issue that just showed up yesterday:
I attempt to open up the DuIK Bassel 2 window and it shows me this message "Unable to execute script at line 319. p is undefined".

After closing the message the script window appears bur empty.

The same happens with any optional panel.

The weird part is that a couple of days ago it was working just fine.

Just for the record:
- I'm using AE on Windows 10;
- The "Allow Scripts to Write files and Access Network" option is checked;

- I've already tried redownloading/installing duik;
- I updated AE 28 days ago and the issue didn't happen then. It only started yesterday.

Could anyone please help me?
I got so addicted to control keyframes and timing with DuIK's animation panel I don't know how to use AE otherwise anymore and al other scripts for controling keyframes stink.
DuIK is irreplaceable.
