Error occurs when try to save a NeoOffice document

Hello,
I am running Mini Duo OS 10.4.7 and have installed NeoOffice 2.0 Aqua Beta 3.
I often get this weird error message when I try to save a NeoOffice document.
What could be the cause?
Can I get any solution to fix this problem?
I extremely need your assistance ASAP.
Any idea would be appreciated. Thanks.
