[Closed] Readline with max 2012

Hi guys

   I have a problem with a function that works in max2011 alright, but fails in 2012. And I am unsure where the actual error is. All I am trying to do is write a password into a file, then open the file again and check the password. Pretty straight forward process:

       fn register =
       (
       	pw = "I am the password" -- some password
       	regfile = createfile (getDir #temp + "\\license.tmp") -- create a temporary license file
       	format pw to:regfile -- write the password into the file
       	encryptfile (getDir #temp + "\\license.tmp") (getDir #temp + "\\license.lic") 1234567 -- make an encrypted version
       	close regfile -- close the temporary file..
       	deletefile (getDir #temp + "\\license.tmp") -- ..so that it can be deleted
       )		 
       			
       fn isregistered =
       (
       	registered = false-- create boolean registered
       	if (doesfileexist (getDir #temp + "\\license.lic")) then-- check for file
       	(
       		
       		checkfile = openencryptedfile (getDir #temp + "\\license.lic") 1234567 -- open the license file
       		password = readline checkfile -- read the first line, containing the password
       		close checkfile -- close the file again
       		if password == "I am the password" then registered = true -- if it matches, registering worked
       		
       	)
         if registered then messagebox "hooray, it works"		
       )	
       
       register()
       isregistered()

   So if you run the code in max 2011 you should get a messagebox saying "hooray, it works". One would think the same applies to max 2012, but there I get:

-- [color=Red]Error occurred in isregistered(); filename: D:\Projekte\3dsmax\scripts\registertest.ms; position: 826; line: 20[/color]
       --  Frame:
       --   registered: false
       --   checkfile: <File:C:\Users\David\AppData\Local\Autodesk\3dsMax\2012 - 64bit\enu	emp\license.lic>
       --   password: undefined
       -- Runtime error: Read past end of file

   What could be the explanation? It must be something 2012 specific, I guess.

   thanks, David
