Hi all, I am new to this forum. I purchased an Opus 500 system 3 years ago and it has been working fine until recently. One of the WCU 500 control units failed! I contacted Opus at the beginning of the year but, was informed that the company was no more. They are not doing any repairs or replacements!!! I was told to contact some of the dealers to see if they have stock. This has yielded no results!! Yesterday the second WCU 500 unit displayed a message on the screen,'Ready For Download.' It has stopped working completely other than displaying the message. First of all, the company that did the installation went bankrupt two years ago. With Opus now defunct, I don't where else to go for help. Does anyone have solution?
