I am using Creo Schematics Release 7.0 and Datecode7.0.0.0

I have a file which appears to be corrupted it should have 8 design sheets but it will only open 7 of the 8 sheets. The file produces the C++ assert failure which crashes Creo Schematics. We will recreate the design. But how do we prevent this as this message C++ assert failure, appears more frequently with Creo Schematics 7.0 (was never in Schematics 4.0). And the design has internal error 002 when you open it. But cannot do design check to repair because it gives C++ assert failure and crashes. How to resolve or work around this issue?

Here are the errors that I faced
Internal Error 002, C++ assert failure

Hi VladimirN, The article link you sent is referring to Creo Parametric. I did a search and do not see any articles related to this issue in Creo Schematics. On a side note, when I did a save as in Schematics and saved as a packed design to my local drive, upon opening the packed design all sheets were present. Could it be this is a work around to resolve the corrupted file?
