CANNOT DELETE A RECORD - BUG

This message was posted elsewhere but after struggling with the problem for few days (including export/import App) I consider this to be a bug. I have no access to source and no matter what I do I get the same error. It seems that for some reason SC keeps adding SS library (which obviously has a bug). Even despite this LIB is unchecked from the project.

When trying to deleted record (from the form) I het following error:

Fatal error: Cannot redeclare class scSSN in C:\Program Files (x86)\NetMake\v81\wwwroot\scriptcase\app\TECREP\fm _c_expcategory\sc_ssn.php on line 3

The form has nothing fancy, no extra code or libs. Of course PHP file is obfuscated so cannot see the code, although
the beginning start from this

class scSSN{

    // Populate this variable with the high group list provided by the Social Security Administration:
    // http://www.ssa.gov/employer/ssnvhighgroup.htm

    // We only want the numbers. Omit the explanatory text at the beginning of the file.
    // This list is from May 2008
    private $highgroup =
'001 08  002 06    003 06    004 11    005 11*    006 08
007 08    008 92    009 92  010 92  011 92  012 92
013 92    014 92    015 92    016 92    017 92    018 92
019 92    020 92*    021 90    022 90    023 90    024 90


and obviously line 3 says nothing and the sc_ssn.php is unchecked

Any ideas how to get rid of this ?

PS> Admin - please remove the message posted in General SC forum.
