Out of memory – code 0x3C5A71C9 ERROR in PagePlus Home Office Edition

Hi! I decided to treat myself to a AMD Athlon 850, Now when I start PagePlus Home Office Edition I get an error message that says: "Out of memory – code 0x3C5A71C9" On clicking on OK everything appears to work normally. Can anyone help me with this? What does the error mean?
