Something weird is going on.

hey i'm no expert but why don't you try the newer ums versions to see if there is any of them that you can make it work and since ums operates with java try to install the newer versions of it. i know it's not much but at least you can try i hope it helps somehow. i'm having some trouble too since the media player for the ps4 updated to the version 4.01 my m2ts files are not working well for some reason they slown down this isn't happening before it sucks bad. i've tried to go back to older versions but still happens.

It would be useful to have logs of when UMS fails to start, instructions are in the Problem Reporting Guidelines above
