MySql Log File Error

[Macey Macintosh]

Hello! I'm a brand-new MySql user. Yesterday I started up wiki based of of my local server, and it worked beautifully (no errors). But today I tried to get it started up and I keep getting the infamous "Unexpected end of MySql... see log file?". I've tried everything the interwebs suggested, such as changing user permissions, restarting Apache and my computer, and I just tried to take a look at the log file to see what was up. It's repeating itself, but there seem to be two main errors:

3-05-21 16:02:43 2ac InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
2013-05-21 16:02:43 2ac InnoDB: Recalculation of persistent statistics requested for table "my_wiki"."objectcache" but the required persistent statistics storage is not present or is corrupted. Using transient stats instead.

2013-05-22 09:35:03 2876 [Note] InnoDB: Reading tablespace information from the .ibd files...
2013-05-22 09:35:03 2876 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace mysql/innodb_table_stats uses space ID: 1 at filepath: .\mysql\innodb_table_stats.ibd. Cannot open tablespace my_wiki/user which uses space ID: 1 at filepath: .\my_wiki\user.ibd
InnoDB: Error: could not open single-table tablespace file .\my_wiki\user.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'm not sure what program you can use to open an .ibd file (namely the user.ibd file), and when I tried to open it with jEdit the encoding was screwed up. I would really appreciate some help! I'm completely lost.

Thank you!
