Applescript stopped working, error -1708

Question

Hi,
Applescript has stopped functioning on my computer as of yesterday.
No applescripts are working. The problem has appeared on four other Macs in our office.
Here is a sample of what I am seeing running the script in ScriptEditor:
tell application "Finder"
          try
       mount volume "afp://10.143.2.217/Production_FP/"
  end try
end tell
Results in:
tell application "Finder"
mount volume "afp://10.143.2.217/Production_FP/"
  --> error number -1708
«event ascrgdut»
  --> error number -1708
mount volume "afp://10.143.2.217/Production_FP/"
  --> error number -1708
end tell
I am seeing the same error code whatever AppleScript I run.
Running on a Mac Pro 2.26 GHz Quad-Core Intel Xeon, MacOS 10.8.4.
I have restored various files from the Time Machine backup, but none of them has fixed the problem.
Could anyone please tell me which files I should try to restore, or any other way to fix the problem.

Here is another sample of the error.
This is from a a script to create a slug in InDesign.
tell application "Adobe InDesign CS6"
          get font "Arial Narrow"
                    --> font "Arial Narrow"
          set properties of text defaults of active document to {applied font:font "Arial Narrow", font style:"regular", capitalization:normal, justification:left}
          activate
          get active document
                    --> document id 1
          count every page of active document
                    --> 1
          get page 1 of active document
                    --> page id 208 of spread id 203 of document id 1
          get layer "Slug" of document id 1
                    --> layer id 261 of document id 1
          set active layer of active window to layer "Slug" of document id 1
          get name of document id 1
                    --> "Untitled-1"
          exists swatch "sluggreen" of document id 1
                    --> true
          exists swatch "slugorange" of document id 1
                    --> true
          get active page of active window
                    --> page id 208 of spread id 203 of document id 1
          set slug bottom offset of document preferences of document id 1 to "40mm"
          set slug top offset of document preferences of document id 1 to "10mm"
          set slug inside or left offset of document preferences of document id 1 to "10mm"
          set slug right or outside offset of document preferences of document id 1 to "10mm"
          set horizontal measurement units of view preferences of document id 1 to millimeters
          set vertical measurement units of view preferences of document id 1 to millimeters
          get page width of document preferences of document id 1
                    --> 419.999999999167
          get page height of document preferences of document id 1
                    --> 296.999999999461
          round 419.999999999167
                    --> error number -1708
          «event ascrgdut»
                    --> error number -1708
          round 419.999999999167
                    --> error number -1708
Result:
error "Adobe InDesign CS6 got an error: 419.999999999167 doesn’t understand the round message." number -1708 from 419.999999999167
It is also not running any of the applescripts I use within FileMaker Pro.
Here is a sample of one I use to create folders on our server:
tell current application
do shell script "mkdir '/Volumes/Production_FP/test' 2> /dev/null"
Result:
error "\"mkdir '/Volumes/Production_FP/test' 2> /dev/null\" doesn’t understand the do shell script message." number -1708 from "mkdir '/Volumes/Production_FP/test' 2> /dev/null"
All these scripts did work a few days ago, and still work on other identical computers.
I have tried replacing the System/Library/ScriptingAdditions folder from the Time Machine backup, but this has not helped.
