So yesterday I was working on my project, everything went fine, so I just went to sleep. I woke up, done my things and when I tried to run apache and mysql (through xampp), apache did start, but mysql shows an error like this:

Error: MySQL shutdown unexpectedly.
[mysql]     This may be due to a blocked port, missing dependencies, 
[mysql]     improper privileges, a crash, or a shutdown by another method.
[mysql]     Press the Logs button to view error logs and check
[mysql]     the Windows Event Viewer for more clues
[mysql]     If you need more help, copy and post this
[mysql]     entire log window on the forums

I did absolutely nothing since yesterday, so I have no idea what went wrong. Also, I've checked Windows Event Viewer, and came up with those results:

Warning
Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--log-basename=#' or '--relay-log=mysql-relay-bin' to avoid this problem. 

Error (this one repeats itself couple of times)

Last two errors repeats themselves 4 times alternately (but with slight different values)

Could you guys help me with this one? I dont want to lost all of my data. Already tried reinstalling and copying content of mysql->data but it doesnt work.

With mysql not started, check if there xampp/mysql/data/multi-master.info file exists, and delete it. This worked for me.
