 * Hi,
    I’m trying to instal your plug-in on my WP 4.0 running twenty-ten theme.
   Installation says it goes OK, but when I activate, I get:
 * > Warning: include_once(/var/sites/c/mysite.org.uk/public_html/Newsite/wp-content/
   > plugins/pedalon-rm/classes/prm-pack.php) [function.include-once]: failed to

   > Newsite/wp-content/plugins/pedal-on-race-management/pedalon-rm.php on line 
   > 397

   > Newsite/wp-content/plugins/pedal-on-race-management/pedalon-rm.php on line 
   > 398
 *  Any advice appreciated.
 * EDIT:Please forget this – just installed the update to 1.1. and it’s working 
   fine now.
