So I have a customers files that I can't open... 180mb .pdf. Every time I try to open the files I get "Out of Memory" message. I had the same problem with another file from the same customer, but was able to open it on my mac from home. I wondering if it would open differently with a newer version of illustrator? I'm using cs4. The files also say they were created with a newer version of illustrator, but I was able to open one from home and I'm running cs3 on my mac... Can anyone give me any ideas on ways to open this file? Or possibly let me send it to someone with a newer version of illy and let them try to open??
