Photo Gallery: Can’t add photos, can’t find some I added previously

I have been using photo gallery for about 6 months . I have a lenovo computer with

windows 7. After i have imported my photos from my Kodak Easy share i am prompted

to organize,edit and share my photos with Photo Gallery. No problem until the last group of photos.

I get an unable to ad photos to gallery message.  I am unable to even find the photos I just took 

on my computer to place in my E-Bay ads.  I was thinking that the   Photo Gallery 

software i have might have been a trial that ran out. Do i have to pay for this service

or is it free?  Thanks a lot for your help!  Carol Ferguson

Moved from Windows 7
