transient file openning problem

EAR

Hi guys, I am calculating flow in the pump with star-cd 3.26 (XP64 OS). I am running the solver with 5cycle rotation(1800deg) and the number of time steps are 3600(time step for period is 0.5deg). it saves data every 5degree. Calculation is converge after 3600 time step. for loading transient data: 1) i select Transient "analysis" 2) I select 1 from "transient post file(s) 3) I select yes from "moving mesh" 4) I click the "add file to list" 5) I click the "open transient post file"

after that all time steps appeared in the "select time step" list, but I just can open only the results from between 1 to 650 time steps, when i open another from 660-3600 time steps it says, "**ERROR-reading post file Incomplete or corrupted data"

what problem maybe with this? please some1 advice
