Cannot input a multiple properties listing

[Jose Valmana]

Hello everyone.  Just became a Plus member yesterday with the intent of posting a package of properties.  System says "There was a problem creating your listing. Detail invalid".  It doesn't say what the detail is.  I have lowered the price, square footage, rental amount, input different addresses, including generic ones, used Chrome & Firefox, overall spent already two hrs trying, but nothing works.  There is no support link here and in the About Us link, I messaged a few of the "support" faces there, but they have not replied.  

Can any of you suggest me what may be wrong, or a way to obtain support?  If I don't see the light today I will need to cancel.  Thank you in advance
