EZPDF类问题

uhm, I need some help here guys, any help would be appreciated. I've been using ezpdf class to generate pdf as a report. Unfortunately, for some reason, I decided to upgrade and move my hosting. All back up (from previous hosting) and restore (to new hosting) success with no problem at all. But then, when I try to generate report, something wrong appeared on my screen. The screen previewing junk code rather than my pdf report. I have checked all my codes, and there is no changes at all. The only thing changed was, the old server based on windows, and the new server based on linux. I'm wondering, did the OS changes affect the pdf class?

Oh, here is my "junk pdf" php page : http://xclient.godadix.com/app/cetak_iuim.php?id=13.2.2/0017/601/2013

Please help me to find a clue about this problem. Thanks in advance.
