Lightroom 4 had a bug that was corrected in the 4.1 update. Just run the update.
I don't think this is a forum that discusses pirated software.
Thank you. I'll try it. This is not pirated sofware though. My sister previsously had pirated stuff on our comp. I was wondering if it was effecting my purchase of Lightroom 4 and Silver Efex in an unknown way.
It worked! Finally. Thank you so much! I was about to pay the computer repair guy to fix it. Thank you!
