I downloaded a trial of lightroom 4 today on my mac running V 10.6.8. I installed and it told me to either login or create an adobe account, I created an account and started running lightroom.
I uploaded a couple hundred pictures from an SD card and noticed that nothing was showing up on my film strip, and therefore I couldn't use the develop area (although I did get there once, but I can't remember how). I googled a bit and someone said they had a similar problem and restarting lightroom did the trick. So I shut down lightroom, restarted it, and it brought me back to the original 'liscense or try' window but told me my trial had 0 days left and if I wanted to keep using it I had to enter a serial number.
I've spent about 2 hours calling adobe, being transfered, having my calls dropped, and now customer service is closed. So I thought you guys might be able to help me?
Also, I moved lightroom to the trash, emptied it, and reinstalled but I'm still getting the same '0 days left' message.
