I uninstalled Paper Machines completely before re-installing the newest version. I tried to extract text from my folder in Zotero. The tab opened, but the progress bar seems stopped at a certain point and will not go further. Looking at the error console in Firefox, there were a lot of warnings (all in the format "Error in parsing value for 'xyz'. Declaration dropped." But there was only this one Message:
C:\Windows\system32\javaw.exe -Xmx256m -Dfile.encoding=UTF8 -jar C:\Users\brekhusr\AppData\Roaming\Mozilla\Firefox\Profiles\aqtfs1xu.default\zotero\papermachines\processors\jython.jar C:\Users\brekhusr\AppData\Roaming\Mozilla\Firefox\Profiles\aqtfs1xu.default\zotero\papermachines\processors\extract.py C:\Users\brekhusr\AppData\Roaming\Mozilla\Firefox\Profiles\aqtfs1xu.default\zotero\papermachines\args\a84f37b0.json
I just tried with a completely fresh install on a Vista machine and
couldn't replicate the errors you're encountering.
I know you're under a time constraint -- would you be able to do Skype or a
Google+ hangout so that I can help you troubleshoot?
