Great! I’m pleased the issue is now resolved for you!
I will update our 3dsMax docs to explain this situation. Thanks.
I just read through this post since we are suddenly getting this error also.
Was the “Kill ADSK Comms Center Process” the answer to this problem?
I’m getting this error now as well on an EC2 instance, a locl machine seems to render fine.
When I change max.exe’s thread prio from BelowNormal to Normal it is happening less but it’s not a reliably fix.
I’ve tried the com center kill option and spent a few hours trying to hunt it down without luck.
The error print out happens at the line marked ‘<— here’ so something in that try block is erroring out.

return "undefined"[/code]I think I’ve solved it for my situation… on the EC2 instance I sort or disabled the comm center long before I started using deadline by putting a dummy exe in place there (a simple ‘rename’ stopped working when AD decided to put a check on this and replace the exe when it was missing… what are they thikning?)
Anyways, now I’ve put back the original exe and let DL nuke it form orbit and all seems fine now.
Glad you got it Jonathan. It’d have taken me awhile to hunt that one down 
@ruffstuff, how are things on your end?
