Sql error

Hi,
After posting a couple of questions and not getting replies I have been having a dig around to what my issues are.
The problem: Working on Wamp local host to build a website, all went well until I took a look at adding subdomains. Anyway, after a frustrating few hours I am now left with no access to any of my local host areas and this showed up as 403 Forbidden and now after a bit of adjusting I get 404 Not Found Error.
I feel that if I go any further I will totally screw up.
I have checked my Sql and on the log there is this error:

140305 21:15:07 [ERROR] Cannot find or open table gallery/wp_sitemeta from
the internal data dictionary of InnoDB though the .frm file for the
table exists. Maybe you have deleted and recreated InnoDB data
files but have forgotten to delete the corresponding .frm files
of InnoDB tables, or you have moved .frm files to another database?
or, the table contains indexes that this version of the engine
doesn’t support.

I am now totally frustrated as what was going so well has turned into a bit of a nightmare. Any assistance would be welcome.
Thanks
