SSRS 2008 - PDF files cannot be opened

Question

Hi there,

For some time, PDF files generated with SSRS 2008 do not open in most versions of Acrobat Reader (it used to work with almost all versions of Acrobat Reader) Acrobat Reader 5, 8.1.3, 9.1.3, 9.2, Foxit Reader : works fine Acrobat 8.x (other than 8.1.3), 9.1.0, 9.3 : does not work, Acrobat Reader freezes. Sometimes it eventually works. Same thing when generated directly by the report viewer.

Acrobat Pro Extender says the PDF files have no default.

We must have done something on the reports, but what ? Any idea about where to look ? Do you know of any solution that could "repair" PDF files ? (We tried Advanced PDF Repair, but the fixed files do not work better...).

Thanks in advance
