<p>Hi,</p><p>I have recently begun usin OpenLP in our church and it works great on my Win 7 laptop with no problems at all. I also want to use it on an old XP laptop though and with this I get problems whenever I get to a powerpoint show within the service. OpenLP gives me the following error:</p><p>Traceback (most recent call last):</p><p style="margin: 0px; text-indent: 0px;">File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\out01-PYZ.pyz\openlp.plugins.presentations.lib.messagelistener", line 293, in startup</p><p style="margin: 0px; text-indent: 0px;">File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\out01-PYZ.pyz\openlp.plugins.presentations.lib.messagelistener", line 65, in add_handler</p><p style="margin: 0px; text-indent: 0px;">File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\out01-PYZ.pyz\openlp.plugins.presentations.lib.powerpointcontroller", line 138, in load_presentation</p><p style="margin: 0px; text-indent: 0px;">File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\out01-PYZ.pyz\openlp.plugins.presentations.lib.powerpointcontroller", line 159, in create_thumbnails</p><p style="margin: 0px; text-indent: 0px;">File "<COMObject <unknown>>", line 3, in Export</p><p style="margin: 0px; text-indent: 0px;">com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft PowerPoint 2010', u'Slide.Export : The path or file name for C://Documents%20and%20Settings/Projector/My%20Documents/Dropbox/OpenLP%20Files/data/presentations/thumbnails/Acts.4.22.12.pptx/slide1.png is invalid.
