Help with KnotTheory

Hi Dror,
	Here I’ve included several of the inputs that I’ve tried along with all the path information and folder placement information. Thank you so much for your help.

$Path

This is my Path variable, the folder KnotTheory is in /Users/Deaupreme (my home folder). So Mathematica should know where it is.

<< KnotTheory`

As you can see the welcome message does print, and when I type a command from the package Mathematica recognizes it, but there are these red error messages which I don’t understand.

Alexander[Knot[6,2]][t]

Following the Setup Page on Knot atlas I tried this example and the output is correct, but I get these weird error messages too.

KnotTheoryVersion[]

This is the version I found on the Knot atlas, I assume it’s the most up to date one.

KnotTheoryDirectory[]

This looks like it might be a problem, I gather it should spit out a path?

Now for the bigger stuff ...

KnotInput[]

So here’s the graphical input function which returns more error messages.

PD[DTCode[-4,-6,-2]]

Alexander[PD[X[1,4,2,5],X[3,6,4,1],X[5,2,6,3]]][t]

On the other hand this portion seems to work just fine. The DT code here is for the trefoil. Then we try the Khovanov Homology routines (this is my primary interest in the package).

Kh[PD[X[1,4,2,5],X[3,6,4,1],X[5,2,6,3]]][q,t]

and we get this weird mess of errors.

sInvariant[PD[X[1,4,2,5],X[3,6,4,1],X[5,2,6,3]]]

Same problem for the s-Invariant function. It’s strange to me how some of the commands seem to go through fine, but the larger routines don’t work. I notice that the phrase (MessageTemplate[Get, path, "\!\(\*RowBox[{\"ParentDirectory\", \"[\", \"File\", \"]\"}]\) in $Path is not a string.", , , , , Local])
seems to appear early on in all the lists of errors, but I’m not sure what it’s saying or how to fix it. 

If there’s anything else you’d like to know about my set up I’m happy to let you know. Thank you again for helping me with this.
