warning: include_once(sites/all/modules/date/theme/theme.inc) [function.include-once]:

Hi,

I just updated my site and all seemed to go well,
I noticed a few errors after updating the date module

warning: include_once(sites/all/modules/date/theme/theme.inc) [function.include-once]: failed to open stream: No such file or directory in /home/xxx/public_html/main/includes/theme.inc on line 286.

warning: include_once() [function.include]: Failed opening 'sites/all/modules/date/theme/theme.inc' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/xxx/public_html/main/includes/theme.inc on line 286.

Those files appear to be in the directories

Any sugestions please?

EDIT,
Got frustrated..
I reinstalled the date module, this sorted the problem.
