Help! Problem with additional voices in OS X Lion

😕

I have installed some additional voices via TTS utility in Settings, but after

installation is finished I can't choose them from drop-down menu - they disappear right after being chosen. Finally only Alex voice is accessible for use.

Repairing permissions doesn't help, reinstalling voices doesn't help too.

In console I have found some strings following this faulty behavior:

30/07/11 17:20:32,354 [0x0-0x1be1be].com.apple.systempreferences: FBundle 0x4001e7040 </System/Library/Speech/Voices/Thomas.SpeechVoice> (not loaded)

30/07/11 17:21:05,331 [0x0-0x1be1be].com.apple.systempreferences: ystem/Library/Speech/Voices/Thomas.SpeechVoice> (not loaded)

30/07/11 17:21:05,330 [0x0-0x1be1be].com.apple.systempreferences: MLWR init error: 80000012

Any your suggestions will be very appreciated and thank you in advance for your help!
