I Can't launch fortnite (grey launch button)

since the last update (29 or 30 march) I can’t launch fortnite from my account anymore, the ‘Launch Button’ is grey and i can’t execute it. The description is “Fortnite is actually unvailable to play” can you help me ? :confused: It’s only from my personal account (I never cheat, glitch or something like that ^^') I try to uninstall and install the game from another account, but there was no change…
I contacted the French and English support by mail but I have no answer (it’s been almost 4 days …)
