Business works error ?

I was posting some bills to business works this morning and I am getting this message.
Unable to continue. There is not sufficient space available on
Your hard disk to continue the current operation. You should delete
Unused files to make more room on your disk.

Is this software related or hard drive related? I have tried to find business works tech support but no luck. Any advice you can give me would be greatly appreciated. thanks.

how much space left do you have on your hard drive? Normally you get this error when running out of capacity.

It is saying I still have 53.1 gb free space?
