Recently I'v been getting this problem. The operating system is Windows XP; CAESAR vern 4.30

When I am working on a file (checking the piping in 3d plot view) suddenly an error dialog box pops up with the following message :

CAESAR II application has encountered a problem and needs to close. We are sorry for the inconvenience.
Please tell microsoft about this problem.

On checking the error details, they are as follows :
Error signature : prepipe.exe
Appver : 4.1.0.0
ModName : hoops500.dll
ModVer : 500.34.0.0
offset : 0002f017

The instruction at 0x5f401351 referenced memory at 0x00000004. The memory could not be read.

----------------------------------------------
I have tried reinstalling the program to no avail.

Will someone kindly throw some light on the problem.

TIA
