On FireFox's sync site, it endorses web2pdf. It doesn't work and it prevents my making PDFs with Adobe. So I got rid of web2pdf by closing out the add-on. That uninstalled the add-on, but I still can't print out any pdfs. I removed Shockwave Flash 11.5 r502, couldn't find Shockwave Flash 9.0 r45, and didn't understand the Mozilla page on plug-ins. "Adobe PDF Properties" tells me my PDF printer is working properly, but when I attempt to print a PDF, I get a pop-up window that informs me of an "error printing PDF." If I try again, the popup window tells me that my "Adobe PDF" is in "error status" until I remove the queued document. I never had this problem before I downloaded print 2pdf, and now that I've uninstalled it, the problem remains. How do I regain my Adobe PDF function? Any steps I can take to set my system back to its original operational state? Would reloading my Adobe CS3 solve the problem? Is there anything I should/can do before I resort to that (a very timely process)? My OS is Win8.
