Hi,
Take a backup of Ampps\mysql\data folder before doing anything.
The workaround/solution can be found here itself in log.

2013-10-19 06:50:53 3712 [ERROR] InnoDB: Attempted to open a previously
opened tablespace. Previous tablespace gazelle/api_applications uses
space ID: 5 at filepath: .\gazelle\api_applications.ibd. Cannot open
tablespace mysql/slave_worker_info which uses space ID: 5 at filepath:
.\mysql\slave_worker_info.ibd
InnoDB: Error: could not open single-table tablespace file .\mysql\slave_worker_info.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.
