Can an older woman learn to use her computer programs

I've been using the computer for several years and think I can handle e-mail and surfing the internet.  But, I think I've met my match as of yesterday.  I took an EQ7 class, (for those non quilters out there, it's a computer program to help a quilter design her own quilt pattern) did all the things the instructor told me to do and I was successful at it.  I return home and tried to do all the fun things on my PC that I did on my lap top and guess what!  NOTHING WORKED!  Since I just had a birthday and we'll let be that I'm closer to 60 than I am to 50, I'm wondering does that mean my brain can't absorb anything more??  We shall see as each day I'm going to give it the old college try and see if I can come up with my own quilt design sooner rather than later.  As we know life is fleeting and I really want to say I've made that quilt from design to finish!  Wish me luck.
