This will probably not fix your problem, but you should always update
your system and keep it on the latest point release, in this case,
4.7, or very soon 4.8 which is going to be release.

The differences between 4.4 and 4.8 should keep the same base versions
of applications and libraries, so they should not "break" anything
that is currently working on your machine right now (but if the system
is critical you might decide to test the upgrade in a test environment
first.) On the other hand, if you are still running software from 4.4,
there are know bugs and exploits to which your machine is vulnerable,
and it is in more risk of being attacked than if it were fully
updated.

HTH,
