How to fix "Couldn't load plugin ..." and "ImportError: No module named ..." in QGIS plugins?

After installation of Quantum GIS (QGIS) I tried to use Table Manager Module, but I can't do it.

Here is the message:

Nem tudom betölteni a 'tablemanager' modult innen: ['C:/PROGRA~1/Quantum GIS Wroclaw/apps/qgis/./python', 'C:/Users/Tamás/.qgis/python', 'C:/Users/Tamás/.qgis/python/plugins', 'C:/PROGRA~1/Quantum GIS Wroclaw/apps/qgis/./python/plugins', 'C:\PROGRA~1\Quantum GIS Wroclaw\bin\python27.zip', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\DLLs', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\plat-win', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\lib-tk', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\qgis\bin', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages\PIL', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages\win32', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages\win32\lib', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages\Pythonwin', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\Python27\lib\site-packages\wx-2.8-msw-unicode', 'C:\PROGRA~1\Quantum GIS Wroclaw\apps\qgis\python\plugins\fTools\tools']
