Unable to see a video on chromecast using UMS

[Gotrunks]

Hello,
I was a big fan of PMS that I used a lot with my PS3 and wanted to try UMS 5.1.4 (on windows 7 64 bits) to use it with my chromecast. The problem is, when I try to launch a video I have the loading animation on my TV for one second then the chromecast logo and nothing happens, UMS just freezes for 20 seconds. I used several format of videos so it shouldn't be the problem. I installed Bubble UPNP on my smartphone to test, the media is detected by UMS but nothing happens too when I launch video, UMS and Bubble UPNP just freeze for 20 seconds.
I want to add that UMS doesn't even detect my PS3 when PMS still detects it instantly. I'm also able to cast from Bubble UPNP to my chromecast perfectly. I watched the logs a little and I saw things that should never be there like BFM TV or France 24 so I'm lost. Can someone help me please ?

Same problem here. Starts loading, then chromecast logo, then nothing. Btw, the small window from the PC freezes.
