Error message popping out while using Caesar II ver 5.2
I am a user of Caesar II version 5.2 for some days now for the pipe stress analysis and it has been working exceptionally without any trouble. Just yesterday, an error message started popping up on my screen, whenever I start the software. The screenshot of the error is as follows:
The program has encountered an unrecoverable error. The error number is: 258
After this error, the program gets stuck and the system stops responding. The only option is a forced shutdown.
Any suggestions will be highly praised.
Waiting for your response.
