Thank you for your question. I look forward to working with you to provide you the information you are seeking.
What you are being told is your matter is considered "res judicata" and it means that when someone sues for a tort or breach of warranty, which is what you did at the time, it was up to you to have discovered everything wrong with the product at the time you sued. If you did not find the problems thoroughly before the first suit, the court considers any further suits on the same item to be "already decided" or "res judicata."
I truly aim to please you as a customer, but please keep in mind that I do not know what you already know or don't know, or with what you need help, unless you tell me. Please consider that I am answering the question or question that is posed in your posting based upon my reading of your post and sometimes misunderstandings can occur. If I did not answer the question you thought you were asking, please respond with the specific question you wanted answered.
Kindly remember the ONLY WAY experts receive any credit at all for spending time with customers is if you click on OK, GOOD or EXCELLENT SERVICE even though you have made a deposit or are a subscription customer. YOU MUST COMPLETE THE RATING FOR THE EXPERT TO RECEIVE ANY CREDIT, if not the site keeps your money on deposit.
Also remember, sometimes the law does not support what we want it to support, but that is not the fault of the person answering the question, so please be courteous.
