First of all let me thank you. As I am newborn on MS project probably I need more detailed advise which you tired to explain me above. Please be advised that I am using shared resource pool from my MUSTER project and one of the SUB project file has resource names. Also strange thing is that despite of error the MS project still saves information which I added previously. And somehow in CALCULATION option is turned OFF (don’t sure how) which means I have to go to Options section to changes settings everytime when I am opening file after file crash.
Your help and support are appreciated. Thanks again
