Upgrading Lightroom from 5.0 to 5.7.1 [Serial number invalid]

[StevenBaylor83]

Hello, I know this is probably just a problem I'm having but I'm trying to update to the latest version of LIghtroom 5 and I'm having issues.

I'm downloading version 5.7.1 from this link:

http://trials3.adobe.com/AdobeProducts/LTRM/5_7_1/osx10/Lightroom_5_CCM_LS11.dmg

When I install it. I get asked for a serial number which I have.

However, it tells me my number is invalid. Is it too late to update my version of lightroom?

You have either typed in one or more number characters wrong or it is an Upgrade serial number for LR 5 and you have not entered a qualifying previous version serial number correctly.

Do you still have your receipt from the purchase of your previous version? If yes, you may need to contact Adobe here either by phone or chat:
