IntelliJ, Alt + Enter does not work

When you work with IntelliJ on a JavaProject, it shows the use of alt + enter to import a class, for example, but that doesn't work anymore.

It worked in the past, but something had to change,
- the label is still installed,
- another shortcut will work - I can not assign alt + to enter manually, although if I reset by default, it will be installed on it, ideas how to fix my problem?
btw my keyboard layout is german but i don't think this is a problem because it worked in the past, my os won 7.

edited: when I work in the IDE and, for example, write
Arrays.toString(a);
and have not imported "java.util.Arrays" yet, the IDE says:

"? java.util.Arrays? Alt + Eingabe" & ensp; & ensp; & ensp; (Eingabe = Enter in German)

so when I assign a different shortcut, it works, but it does not do with Alt + Enter - thanks in advance for any help.

"Well, that means the IDE for some reason does not see the shortcut. Perhaps it is already being used by some other application or operating system. - CrazyCoder 25 minutes ago."

i closed all applications, and it turns out that Facebook GameRoom running in the background, for some reason, is the reason that the shortcut does not work, I have no idea why, but this solution

many thanks CrazyCoder

He worked before, but stopped working for an unknown reason,

One workaround is Try fn+Alt+Enter

I have the same problem
and it turned out to be the keyboard language in Windows , it was not English,
so just make sure you are in english

In my case, I matched Alt+Enter with the system shortcut (to expand the current window) and forgot. So it may not be another program, but your past sabotages you.
