The remote procedure call failed. (Exception of HRESULT: 0x800706BE)

when calling           

Document idDoc = (Document)idApp.Open(inddTemplate, false);

sometimes COMException is produced:

The remote procedure call failed. (Exception of HRESULT: 0x800706BE)

Some stacktrace:

at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[]

aWrapperTypes, MessageData& msgData)

bei InDesign._Application.Open(Object From, Boolean ShowingWindow)

This error does not appear everytime. We tried to reinstall InDesign (Adobe Indesign CS3 trial Version 5.0.2) but it not helped

I found the same problem in other thread http://forums.adobe.com/message/1307758#1307758

But i did not find the answer.

thanks in advance
