download failed

dear all,
i have problem in downloading result by using Dmol3 for example in calculating Energy such as density of state (DOS), optics and some others.
 
Before i run for DOS, i have run for Geometry Optimization, and it is successfully calculated and downloaded the result. 
But when it comes for Energy calculations such as DOS, the result can't download.
i dont know why.

i hope u can solved my problem ASAP

thankyou in advance.
