qgis - Problems with Google layers plugins

I currently use Quantum GIS 1.7.4 at work and I have trouble to open Google layers extension. In fact, when I start QGIS 1.7.4 the following message appears and I cannot use Google layers extension. Would really appreciate if anyone can help me sort this problem out.

Traceback (most recent call last):

  File "C:/PROGRA~2/Quantum GIS Wroclaw/apps/qgis/./python\qgis\utils.py", line 147, in startPlugin
    plugins[packageName].initGui()
  File "C:/Users/JICA/.qgis/python/plugins\GoogleLayers\GoogleLayers.py", line 33, in initGui
    self.sessionid = gmaps.get_sessionid()
  File "C:/Users/JICA/.qgis/python/plugins\GoogleLayers\gmaps.py", line 21, in get_sessionid
    sessionid = t.strftime("%d%m%Y_%H%M%S%s")
ValueError: Invalid format string
