Installation / Activation Issues 1.1.6

I watched the demo and was really hoping this plugin would work. I wanted to give it a try. I’m not a fan of typing in the footnote in the text, the way most plugins seem to do it. This was a new install on WordPress 4.5.3. I have never used this plugin before.

When attempting to install and active I received the following error message:

Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected T_STRING in …/public_html/wp-content/plugins/cm-footnotes/package/cminds-free.php on line 3

I’m not a programmer, but it didn’t look like it was all the important of a line, so I deleted line 3, which read:
namespace com\cminds\package\free\v1_0_7;

When I attempted to activate once again I received the following error:

Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected T_STRING in …/public_html/wp-content/plugins/cm-footnotes/package/cminds-api.php on line 3

Agian, I deleted line 3 from that file, which was the same line:
namespace com\cminds\package\free\v1_0_7;

When I attempted to activate again I received the following error:

Fatal error: Cannot redeclare cminds_show_message() (previously declared in …/public_html/wp-content/plugins/cm-footnotes/functions.php:234) in /home1/gbchror1/public_html/wp-content/plugins/cm-footnotes/package/cminds-api.php on line 1079

I don’t know if the final error was caused by me or not, but I really hope you all can get this working properly.

Thanks.
