Question: Can anyone explain this "kernel" error message from Maple17 and Maple15?

I am having trouble getting a certain Maple worksheet to execute.  Using both Maple17 (I think it is 17.02) installed on two separate PC's at home (XP), and using Maple15 via Citrix from a server maintained by my employer, I get a long error message.  It starts:    "Kernel connection has been lost.  You should save this worksheet and restart Maple.  Executing commands in Maple requires a connection to the Maple kernel.  Firewalls have been known to cause problems with kernel connections in Maple.".  If anyone wants, I can add the entire error message to this question. I don't think I actually have a firewall at home, and this error message doesn't seem to explain why my local copy of Maple is having trouble.

I think I updated my home copy of Maple to Maple 17.02 after I started writing the worksheet and before this problem appeared, so there may be an issue with Maple 17.02.  But this would not seem to explain the trouble I have executing the worksheet using Maple15 via Citrix.

I have uploaded the file.  I removed the output to make it a reasonable length.  I created a "toy" file that plots x^2 from x = 1 to x = 4, and does nothing else, and it works just fine.  I apologize for the length of the file I uploaded, but I don't know exactly what is causing  the error.
