Error in Saving Topaz Adjustments

First of all, my primary problem was solved yesterday by an Expert who had all the replies. But as of today, as I am trying to save my topaz adjustments, I got an error. I tried it with adjust and clean2, but always failed and give me an error:
“Proc Engine: error code:-1000” I click OK and then received another error:
“Could not complete the topaz clean2 command because -Proc Engine error” I don’t know what the error is trying to imply but I really need some help here.
