SOPC program error java.lang.NullPointerException

Hi @ all,

I have a project which was create by a colleague. It worked without any errors. Now I have changed the project to another device (cyclone II to cyclone III). After I had changed the device, SOPC-Builder opens without any problems.

At last I have added 2 vhdl-files to the project, created 2 symbols and added them to my top-level-schematic to start with the pinning.

After all I tried to open SOPC-Builder. But it does not work.

The following errors are coming:

Error: Program Error

Error: Unexpected error reading the ensemble: java.lang.NullPointerException

An unexpected error occured during Open System: java.lang.NullPointerException

java-lang.NullPointerExceptionat com.altera.sopceditor.tools.saveandload.LoadEnsembleTask.run(LoadEnsembleTask.java:155)at com.altera.ui.app.base.EditorTaskRunner$9.run(EditorTaskRunner.java:389)at java.lang.Thread.run(unknown source)

I have absolutely no idea why this error is coming.

Does anybody know why this problem is existing?

It would be very nice to get helpful replies

Thx Spitzinger
