[Plugin: The Events Calendar] error activating plug in

Hi,

I installed, activated and used the plug in and everything worked fine.

However, I now get the error:

=======================
Parse error: syntax error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /home/xxxx/public_html/blog/wp-content/plugins/the-events-calendar/the-events-calendar.php on line 14
=========================

on the site and on the wp-admin page – I cannot login

So,
– I used the file manager to go to wp-content/plugins directory and renamed the directory
– I was able to login to wp-admin
– I deleted the plug in
– I re-installed the plug in (using Add New plug in menuitem from within dashboard menu)
– but it gives the fatal error (above) trying to re-activate

I looked at the-events-calendar.php on line 14 – it was to a class

I am not sure what to do – Please help

Thanks
