Bodyshop sims problem

[Flyleaf]

OK, here is my problem: Sometimes when I start up the Sims 2, and start a family, I go to use some of my Bodyshop sims. Unfortunately, some are not showing up when I go to "use existing Sim". The first time I tried, my self-sim wasn't showing up. The second time, my self-sim did show up, but now the teenage sim I made wasn't showing up, and I couldn't complete my family. The other sims in the family were showing up, however, but I noticed that some of the other sims were missing as well. Oh, and yes, I did make sure that the gender and age were both the same as the sim I wanted to add. What could be the problem?

Start simple....delete the thumbnails, (that's in the thumnail folder)...sometimes they get messed up and show the wrong stuff.

I went ahead and deleted the thumbnails, and it worked perfectly, thank you!
