WotLK Game freezing

[Alesak]

Hello, yesterday I made changes on my characters via Warmane services system. I changed race and name on my DK character and name on my Warr character. Few hours after change game was running okay, but later the game starts to freeze always, when I open character window in game or bag and I mouse over it. In that moment game freeze, sometimes game is restored and sometimes is frozen until it drops. If I do not open character window or bag, the game running okay - I went Icecrown 10 man raid 6 bosses and no problem.
I cleaned Cache directory several times, but it does not help. I did not make any kind of game setup changes since I changed race and names and no change in addons.

Also when I check my gold status through Titan panel the old names of characters (Melnicak, Chloumek) are still displayed and amount of gold is not displayed correctly as visible on the pic: https://ibb.co/HG45xST

I will be grateful for any tips how to fix this problem...

Thanks A.
