Fantom Xa driver for windows 8.1

[ian88]

Hi! since Windows 8.1 upgrade my pc does not recognize my Fantom Xa in midi mode. I can not use the editor, or the librarian or the VST I normally use.
Nor do I find the driver on the official website of Roland ... I'm a bit confused as this me "I stopped" completely my work between the synth and the PC.
I would appreciate you telling me I'm doing wrong.

Thank you very much.
Adrian.
