Hello A.Somhpop
Your Apple ID can be associated with up to 10 devices. Once a new Apple ID is introduced it disables the other Apple ID for 90 days. The article below will give more information on the matter.

Correct. If you changed apple ID's and downloaded past purchases with a different ID then you block the original ID for 90 days.
There is nothing that can be done about it.
Its a security feature implemented by apple to prevent piracy.
You will have to wait 90 days to use your other Apple ID again, and if you download from that one, you will lock the other one for 90 days too.
