EA not attaching to chart

Although my EA compiles without warnings or errors, I cannot attach it to a chart. It returns no errors or anything, but it will not attach. Any advice?

1. compile
2. go to edit then select all
3. then copy
4. go to file then save as in experts file

5...........close out platform........then reopen it
6 it should appear as a highlighted icon in navigator under expert advisors, then it is ready to attach...

I am having the same trouble.

I have used the same EA many times, but for some reason it does not load on the particular demo.

I tried all the steps you suggested, but no luck.

Any other ideas?
