Error in Total Cost after importing

Hi everyone!

Got another question, Something goes wrong when we try to import the schedule from one pc to the other ( we are using stand alone) and when we try to email it to the client. Sometimes the the cost was doubled, sometime it would be lesser or sometimes higher than what we originally input. And the resource assigment changes as if it was being reshuffled.

Right now we try to delete the different versions of the schedule (we store multiple schedule on the EPS as backups as and per revisions we made to compare) includung its corresponding resources.

But still there is a small difference on the final cost like if the original cost of Casework is 69,000.50 it became 69,001.08.

by the we are using same version here at the office 6.0 and the client uses 6.2, but may it be same version importing or not, it doesnt show the same cost

Can you please help me again on this :)

Thank you in advance
