Thanks for your prompt reply. I did wrote to them about the problem, they ask me to try burning a disc with other modules in the main page. I could create or burn an ISO image. Yes they are helpful at first but later until they sent me a new version 15.3 which was not yet on sale for try. With the new version they sent I try out and see whether the problem solve or not, unfortunately this version could not perform what the old version could. I wrote to them about the problem. From that day no response from them till today. I am puzzle what went wrong as v14.8 I could burn and all work without an problem. Well I keep my finger cross hope someone can help.
