I apologize in advance if this is a stupid question, but I am blocked and unable to proceed any further until I know what I am doing wrong. I have the 64-bit safechars plugin in the plugin directory: [C:\Program Files\JPSoft\TCMD17x64\Plugins]dir /a-d Volume in drive C is Everything Serial number is 420a:1d5b Directory of C:\Program Files\JPSoft\TCMD17x64\Plugins\* 9/27/2010 18:42 9,259 4console.txt 3/26/2012 18:55 84,992 4console64.dll 7/22/2014 15:35 44,032 EVENT64.dll 10/31/2014 11:52 41,984 safechars-x64.dll 10/31/2014 11:56 33,648 SafeChars.chm 213,915 bytes in 5 files and 0 dirs 225,280 bytes allocated 651,259,097,088 bytes freeAs can be seen from above; I am using a 64-bit version of Take Command/TCC as can be seen below: TCC 17.00.57 x64 Windows 7 [Version 6.1.7601]Yet I get the following error messages: [Z:\]z:\BuildUniqueSongList.btm TCC: (Sys) Z:\BuildUniqueSongList.btm  Incorrect function.
