unexpected T_PAAMAYIM_NEKUDOTAYIM class-tgm-plugin-activation.php on line 1109

Hi Guys, please help me with this issue:

I have updated my themes replacing the old class-tgm-plugin-activation.php with the new one, and now some of my buyers are getting this error:

Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in theme/include/class-tgm-plugin-activation.php on line 1109

I dont have idea why, the only solution that I can imagine is to give the old version of the class-tgm-plugin-activation.php,

maybe, there are something more to do with the new class-tgm-plugin-activation.php file?
