New Post: Started getting an error using PTE

My computer is running Windows 7 and Microsoft Office 2007. I have been using your PTE for several years with this set up with no issues. Last week I had Visio 2010 installed on my computer and I am now getting the below error when trying to filter a pivot table using the PTE. I'm assuming the install of Visio is what has caused the problem... Its the only thing that I can think of that changed. I uninstalled and reinstalled the lates version 0.8.4.0(32-bit) and I'm still getting the error.

I've become extremely dependant on this extension. Any help getting it working again would be greatly appreciated
