XAMPP/MySQL: could not open single-table tablespace file .\mysql\innodb_index_stats.ibd after restart of MySQL

I've installed Drupal on my local XAMPP Server. It worked all fine, no problems with including and working with the database/site till i restarted XAMPP. Since then I get the following at my logfile:

2013-09-02 16:18:46 2544 [Note] Plugin 'FEDERATED' is disabled.

2013-09-02 16:18:46 3e8 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

2013-09-02 16:18:47 2544 [Note] InnoDB: Reading tablespace information from the .ibd files...

2013-09-02 16:18:47 2544 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace drupal/variable uses space ID: 2 at filepath: .\drupal\variable.ibd. Cannot open tablespace mysql/innodb_index_stats which uses space ID: 2 at filepath: .\mysql\innodb_index_stats.ibd

InnoDB: Error: could not open single-table tablespace file .\mysql\innodb_index_stats.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.

I looked for a solution via google but it seems to be a problem just with the drupal database because it's able to connect with MySQL if I remove the database.

I hope someone could help me :(.

Move (DON'T DELETE) those files, into another folder:


and .ibd files with the same filename:


Try start MySQL.
