My spells aren't working

[DanKovic]

All of my toons are working ok but today I logged one and I've noticed problem, I can't cast any spell, use items from backpack or even mount. Toon name is Vestac.

My client is 5.4.8. and I got it from archive on Pandawow. (I play on x10)

Problem is I can't do anything, when I click on any spell from spellbar or spellbook nothing happens, like spell gets interupted or something, though this problem occured after I won 3 items on black market. I cleared cache, repair character 3 times and still the same. Also was thinking it could be becouse of items so I delete them, nvm that. I honestly think reinstalling the game won't help since it's only on one toon not to whole account. So please, I need help and I want my priest back in game :)
