All of my GLU games suddenly stopped working all at once!!!!!

Hi,

I had these four GLU games installed on my Salaxy S II i9100:

Deer Hunter Reloaded
Frontline Commando
Frontline Commando D-Day
Contract Killer 2

And all of these were working perfectly till this morning. I last played Deer Hunter Reloader and left my phone for a while to refill the energy.

When I got back to the phone in about an hour, Deer Hunter just froze at the starting GLU screen.

I restarted the device and tried again... same issue... freezes at the GLU screen.

Then tried frontline commando... same issue.. freezes with a black screen after the opening video.

Tried D-Day and Contract Killer... same problem... freezes at the starting screen.

Restarted device... disconnected Battery and SD card... connected / disconnected wifi... tried enabling & diasbling mobile Data... cleared application cache... cleared application data... but same result every time.

NOTHING WORKS:(

All other non GLU games are working perfectly.

Please help!
