Hi Anne,
don’t worry, there’s everything fine with your GarageSale 7 license.
If you open GarageSale 7 and select “Enter License Code” from the “GarageSale” menu it should be no problem to enter your GarageSale 7 license. Please make sure you’re actually entering your GarageSale 7 license, not a license for an older version. (I just sent a mail with your GarageSale 7 license to the given email address.)
I am not sure I understood this correctly but if you’re referrring to the field where you enter your license code: That grey placeholder text might be an older license. However, please ignore that placeholder text and actually enter your current GarageSale 7 license code.
Didn’t you delete your GarageSale 7 license through Terminal? That would explain it. However, maybe you’re using macOS 10.13 High Sierra? It’s a known issue with High Sierra that apps “forget” their preferences sporadically. Could you please give the latest beta version of GarageSale 7.0.10 a try:
Regards, Kristian
