ArgumentException: Font ? cannot be found.] (Asp.net Reports)

Hi guys, i have a scary problem, i have used the rdl files of an already existing reports (sql reporting services)

and succesfully converted them (to rdlc files) to asp.net local report (using reportviewer). and it works very good

on the development server,...However, it does not work completely on test(cert) server:

i actually can load the reports, except one which has graphics in it, on the other hand i can not export any of them

(even those reports that can be loaded to a page), so please help me, the point is that i have to have a pretty much of a good idea

before i go to those test server guys, i dont have access to test server myself. i get 4 exception at once, and i get them when i want to export to pdf, not just the graphic one but also all other reports. Interesting point is that the same reports (i mean the original rdl reports on sql reportingservices)

works wel on the same server (test server), that causes me to question whether it is about lack of some font on the server

i appreciate any help or idea's, and thanks:
