did you try to close and relunch the wallet each time the sync is blocked?
you can also delete all files (just keep wallet.dat and save it somewhere else to be safe (usb stick + hdd files crypted...) in c:users/appdata/roaming/x11coin then you reinstall xcapp from xc download website (version 1.15):

Don't worry if you haven't lost your wallet.dat file you are safe.
I did this, and now it did finish syncing.
At the right (transaction) I see my 5 transactions ever made; if you calculate this I should have +2000XC (and a wee bit).
BUT its finished syncing apparently, but i sill have 0 coins in my wallet
