i bought a new laptop a few days ago. i easily migrated LR5 to the new unit. when i tried to open the application, it asked for my serial number which i correctly downloaded--it is listed on the Adobe site. it acknowlegded the number was correct by marking it with a green check, but the said it was 'an update serial number' and demanded the 'original SN' as well. i have no idea what that is since i'm a very longtime LR user and have updated several times, all through the internet, as was my original download many years ago. my Adobe customer page lists only my last update to LR5 and thus lists only that 'update' serial number. the 'original' is nowhere to be found. the Adobe support site (thats a joke right there) gives two options: review similar user problems online through their 'community' (done) and a Chat with a rep option. well ive tried the chat option at different times over several days and consistantly get a dialogue box reading 'Chat is unavailable right now...A rep will be with you shortly'. needless to say, the rep never shows and i'm stuck. they list no email option and certainly no phone number. any ideas would be greatly appreciated!
