HI Sek Can you provide more information so we can help you? Are you "stopping" activities before starting new activities? Depending on your computer, you can usually run a couple of activities at a time but not too many. Which activities don't work at all? What kind of computer are you using? Are you running it in a virtual machine?

I am an education worker in rural area of Cambodia. I am really interested in Soas for my little kids to start with their desktop computer. Our class is starting yet. I have trying to work with soas by myself. For version 3.0 of soas, it does not work well for some activities. They can not be started any more. Also, soas stuck many times. Then, I try soas version 2.0 which I can install in my desktop hard drive. It work faster and more stable, not stuck often. Still, some activities that I download to install did not work. So, what can I do to solve with this problem?
