Error while loading up EA access trial game

No EA Access doesn't need to be loaded, when you start up a game that has a trial it will bring up a box telling you how much time you have left otherwise the game would launch normally if you own it or is part of the EA Access vault.

Is the full game for Madden available in the "EA Access Trial"? My understanding was that only a "trial" was available currently with EA Access and the "trial" versions of Madden normally don't pop achievements until the full game is part of EA Acces

The EA access trials are only available to EA access members. The trial lasts 10 hours and you can also get a discount on the game with EA access. Also, as a reminder, the Sims 4 should be coming to the EA access vault in the near future!

the ones in the Vault are YOURS and they are full unlocked games with achievements.. as for the trials of the pre released. I would assume YES, you can get achievements since EAs statement is if you decide to purchase the game after the 5th day or trial
ends, just continue where you left off...

ALSO... EA updated the infor on EA Access

Games in the Vault will NEVER be taked out of the vault...

The free trial of Unravel is available to download with EA Access. The time-limited 10-hour trial offers subscribers access to the first two levels, with progress able to be carried over to the full game should you decide to pick it up.

So what you have paid for is the EA Access and not the game itself. Still this way you get a 10% discount on the full game if you decide to purchase it.
