Thanks Owen – my teccy from work had checked my pc over last night and there is no fault, or virus or any other problem that could be affecting the software. He installed the replacement software and true to form 3 hours later it failed so I am going to try a different type, luckily Amazon will take back the faulty one, I think my computer spec is way too fast for the software, it is over 3 times the spec needed to run the programme.
Se la vie, will try again when new programme arrives but am keeping clear of Roxio, the customer support is rubbish, the live help does not work and they dont answer e-mails, to phone them costs a small fortune.
