lsp problem. works sometime but not others

[RChalmers2]

I have been using the following lsp routine for years with AutoCAD 2006.  I believe it was given to me by someone from these forums.  It worked perfectly with AutoCAD 2006.

I recently upgraded to AutoCAD 2014.  The lsp now works most of the time but not all the time.  Why would it not work sometimes? It is in the start up suite so it should load when CAD is launched.  In fact, it does load but it doesn't work with every file.

part of the problem is I'm not a programmer, just a guy who knows how to load lsp routines...

Thank you.

;; ;;
;; Uses a Command Reactor to automatically set the active ;;
;; layer upon the user invoking a command. ;;
;; ;;
;; Layer settings are stored in the list at the top of the ;;
;; program. The first entry in the list is the command on ;;
;; which the reactor will trigger, it may use wildcards. ;;
;; The second entry is the name of the layer to be set when ;;
;; the command is called, this layer will be created if ;;
;; not present in the active drawing. ;;
;; ;;
;; The Director is enabled upon loading this program. ;;
;; It may be manually switched ON and OFF by typing ;;
;; 'LDON' and 'LDOFF' respectively at the command line. ;;

;; Layer Data ;;
;; ======================================================== ;;
;; ;;
;; Populate this list with commands for which the current ;;
;; layer should be changed. ;;
;; ;;
;; The first item is the name of a command that will cue a ;;
;; layer change. The command name should be the full command ;;
;; name, not an alias. This command name is not ;;
;; case-sensitive and may use wildcards. ;;
;; ;;
;; e.g. "[DM]TEXT,TEXT" will cue a layer change for the ;;
;; Text, DText and MText commands. ;;
;; ;;
;; e.g. "*LEADER" will cue a layer change for the Leader, ;;
;; QLeader and MLeader commands. ;;
;; ;;
;; The second item is the name of the Layer to be set to ;;
;; current when the command is called. This layer will be ;;
;; created if not present in the active drawing. ;;
