ok so im playing splinter cell double agent i save a game either quick save or a main save i log off and when i come back to it what happens...i end up at the start of the mission again... what is with thisi am getting seriously annoyed at having to redo the missions all over again and im on the easy setting............. i go into mission file click on the last save load and back we are at the beginning...is there something i am doing wrong or is thissome sort of glitch???? any help would be appreciated.......i love the splinter games but i have to admit this one is hacking me off

hi im hoping someone will be able to explain something for me and how i correct it

i have recently bought splinter cell double agent and am on the shanghai mission only problem is when i go to crack the safe nothing happens the instruction to "use the directional keys" doesn't work is this just me doing something wrong or is it some sort of glitch??? i have rebooted and even re started the level to no avail..whereas there are several tasks you have to do this is the one you complete first so its not a case of i have to do something else before the safe cracking(cos i tried that to)...is anyone else having this problem i would appreciate some feedback please.... thanks

anda happy new year to you all
