It looks like a permission denied error from the OS (errcode 13).
First, ensure this assertion is correct by running perror :
> C:\Program Files\EasyPHP-1.8\mysql\bin\perror -s 13
It should answer : " Permission denied "
If not, please tell here what is the actual error message
If yes, ensure your mysql data files are not read-only and that the user under which mysql is run has write access to those files.
