Was wondering if anyone else had a problem with opening the users guide for PAF 18.104.22.168? After I downloaded it the users guide would not open up. The error stated that it did not start with %PDF as I guess these files(Adobe pdf) are supposed to. Tried to open it in version 3 and 4 of Adobe acrobat reader and neither of them would open it. Any suggestions? Is it just my download that messed up? If so I could do it again. Would like to know. Thanks.
