I design on AI and have to save files as a PDF to be read by my control computer on my Trotec SP400, I have just updated my Job Control software and now Adobe locks up each time I try to open the file. Trotec says that no one uses AI, instead Corel which you can print directly from. Is there a work around outside of buying Corel? Is there a reason that Adobe reader, which worked fine is suddenly sick? Tried updating to fresh Adobe reader (not free anymore) and installing my older versions, no fixes yet. Help!
