Card "FREQUENCY" is not allowed for this subcase type.

Hi to everyone
I am running a non linear quasi static analysis on hypermesh 2017 (optistruct) with contact surfaces
When I run the analysis I get the following error:
*** ERROR # 1461 *** in the input data:
Card 'FREQUENCY' is not allowed for this subcase type.
Can someone help me?

Sorry for not explaining myself very well, but the problem is that I haven't assigned any 'FREQUENCY' card, it appears on its own as an error, ergo I didn't put any frequency in the input data but the error says otherwise.
Could you please share the .out file of the run for quick look?
Didn't find anything specific from out file.Please check below post where user able to fix this issue by deleting setting files.

Ok, thank you, I solved from the .fem file deleting the string which contained the frequency card.
Actually, you don't need to assign 'FREQUENCY' in the loadstep definition for a quasi static analysis . That field is for frequency response analysis.
