I tried CHAT SUPPORT first! First agent said after a long conversation with me supplying much information including serial that 'he was unable to help and will pass me to installation agent'. Second was the same, many questions and serial supplied, email etc. Then passed to Adobe Expert telephone number who failed to help and disappeared off telephone line after promising email answer ... no answer came .........
I have now used Adobe Cleaner, if this doesnt work will ask for money back.
