Quartus - assembler not generating sof file

Hi, By default Quartus assembler generates sof file, however, it's no more in our case. Any particular settings that is causing this ? The Quartus I am using is not an evaluation copy. Thank...

To generate a new sof file thanks to start assembler in quartus processing menu,

do I have to open before a specific file from my project ?

because when I open my project .qpf and start assembler it doesn't work

Error: Run Fitter (quartus_fit) before Assembler (quartus_asm)

Error: Quartus II Assembler was unsuccessful. 1 error, 0 warnings

Either the fitter didn't run successfully in the previous attempt or the data base files get corrupted somehow....Please delete the db and incremental db folder and rerun the whole process till fitter.
