[jean mathis] "as I said even with all effects turned off same problem happens"
Sorry, Jean -- I read right over that. Are you sure all effects everywhere are off? If I'm reading the error description correctly, this error should not be thrown unless an effect is invoked.
Have you installed all the updates to AE?
Looking at the PSDs sounds like a good idea -- maybe the problem lies with the PSD importer? If you flatten them to another image format, does it clear up the issue?
In any case, it's certainly a bug, and filing a report might help clear it up in future releases (even if it doesn't help you in your case now).
