Unable to get a trial version of Adobe Indesign CS3

Did u install toshiba driver?

Easiest way is to Export the CS4 file to CS3 Interchange (INX).
The other way is:
InDesign CS3 can obtain the compatibility plug-ins by choosing Help > Updates and following the prompts. Plug-ins can also be installed from the Adobe website: Choose Support > Updates in the Adobe website, and go to the InDesign Downloads page.

Adobe packages have different level of security and you cannot reinstall the trail version after the trial period is over.

has the file been downsaved as inx file from CS3. Then you can download patch from adobe.com to open the file in CS2

manual is built into the applications. Just go to "help"

go to below link and try downloading... CS3 may not be available. You can download CS4

Hi,
Many reasons are there like missing links or third party plugin data.....

one of the solution is,
Whoever created the original document needs to export it as an InDesign interchange file and you should be able to open it in an earlier version of InDesign.

I suggest you to update the CS1 with patch that can be downloaded from the adobe website for reading CS3 INX file.
