Error when try to use ADE simulator to initialize

Hello there,

Before last weekend, everything was fine. The error came with no indication. I tried to modify the cds.lib, .cdsenv and .cdsinit. The error just always there. The problem makes ADE cannot initialize the schematic information, even I load the state manually still not work. I do not know what is the problem. I check the file and file path, they are all correct. My cadence is IC 5.1.41. Thank you very much. It bothers me for almost one week.
