Status change detected: stopped Error: MySQL shutdown unexpe

[dCart]

I have a huge problem with Xampp.
Yesterday in my.ini I changed innodb_lock_wait_timeout from 50 to 100. Then mysql shut down with a message:

Status change detected: stopped
Error: MySQL shutdown unexpectedly.
This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.

the Windows Event Viewer for more clues

I made copies of the files from C:\xampp\mysql\data and deleted them. Then mysql started up but the websites on xampp stopped working.
Websites display mysql error: Table xxx hasn't in engine.



Somebody know how fix it?
