Error Report/Crash Ind CS3/Pagermaker 7.0/can't PDF/or use distiller

Question

In both Adobe Indesign and Adobe Pagemaker I get an error saying....Indesign.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
"If you were in the middle of something, the information you were working on might be lost."
For further information about this error click here
It has a debug button on the left and an option to close the dialog box on the right.
Next I get another dialogue box: error signature
AppName: indesign.exe AppVer:5.0.0458 Mod Name: objectmodel.dll
ModVer: 5.0.0458 Offset: 0001dc8c

I got this message after working in a large indesign file of 50mb with lots of placed PDFs, 500 page document, not in section.
But then I get this error with small pagemaker files, and it seems to be random, not to a particular file or location.
I cannot upgrade to dot versions as the CS3 software is not supported by the IT section of my work.
I work in a security environment and am struggling to produce PDFS, and carry out work on a daily basis.
PLEASE HELP!!!! ( not shouting, just desparate to get this fixed.)
Cheers.

Answer 1

No I am saying that when only Indesign is open it gets the error message.
Which is the same when I only have Indesign open.
My technical officer here won't allow the update because it has not been tested with the security settings in my work environment.
And my colleague who has an identical machine works fine!!
