Export to pdf fail

Hello,

I'm using SQL Reporting services 2000 SP2.
I create a report and when i select pdf format in the export dropdownlist and i click on export, a popup (open/save) appears but when i click ok, i've an error message : "IE can't download Format=PDF of IP_ADRESSE".

If i do the same thing with excel type in the dropdownlist it works!

Do you know why?Have you tried looking in the log files or Event viewer on the server?|||Yes I have an exception in the reporting services log but nothing in the event viewer.
The exception :

It seems to be a problem with the length parameter but i don't known what to do.

Any idea?|||Ok I find th problem.
In my rdl file I have the language define as 'en' and for exporting in pdf the format has to been syntaxed like this: xx-XX.
I put my rdl in en-US and it works.

Thanks @.+|||I found I had put some HTTP headers in at the website level on IIS to disable caching on some non-related ASP applications running in the same IIS instance.

I removed the HTTP headers:

Cache-Control: no-cache

Pragma: no-cache
