Does anyone else have problems using Multiply?

It is very slow to load and to refresh and, frequently, it stops my computer, I have to turn it off and on again.

Any ideas of how to fix/improve this?

Thank you for the help!
Update: I have another open question about Multiply, that still doesn't have all the answers I need. Could you have a look at it, please?

Update 3: UP - Thank you very much!
