Technical Wow error after login

[ezisegyfa]

Hi!

Most of times when I log in to game and choose realm I get wowerror: The memory could not be "written". Sometimes it doesn't happen (one time of 6-7 trying). If I successfully log in and try to choose another character than get wowerror again. I guess it occur while rendering the character to the screen. I tryed to delete wtf, interface and folders, use -noautolaunch64bit parameter in launcher and set the directx version to 9 but doesn't work. I use windows 7 32bit. Any idea?

Another observation is that the error occur just if I select undead character in the character chooser menu. If I choose tauren or blood elf work fine but if I choose an undead char get the error.

You're blocked from playing undead? RACISM!

Where did you save your WoW client? Do you have rights to that location? Have you unchecked read-only from WoW -folder's properties? Have you tried to unstuck your undead?

Thank you for your reply. I saved my wow client to D: drive. I unchecked the read-only property for all file and subfolder in the client and run wow as administrator. Should give other rights to client? The entire error message is: The instruction at "0x0309C352" referenced memory at "0x461F2000". The memory could not be "written". How can I unstuck?
