Save data and continue the motion analysis in Solidworks

Hi,

I have two questions.

1. Saving data in SW

I have one assembly and using motion analysis.  After finishing the analysis, I save all.

After that I choose to rebuild and save document.

Then when open it again,  no result or wrong results are saved.

2. How can I continue the analysis ?

For example, I calculate for 2s. and then I can save the data safely. I want to continue the analysis from 2s to 4s.

How can I do this ?

Thanks in advance for any advice.
