Im really sad):....... please answer!!?

before christmas i played on a game on my psp called monster hunter freedom 2, i soon bought mhf1 because my freind didnt have f2, i played on it for ages then saw trailers online for monster hunter portable 2nd g ( its the japaneese version of the update ) i played on that for ages then in the later 2008, i had a long break... when i decided too give the game another try i got my psp out a bag ( were it was safe ) and decided to change the screensaver which is a sticky pice of clear plastic which i change every now and then. but there was lots of sticky stuff left on the screen! i did what i used to and put white spirit on it to get the glue off and it just made it spread! the glue is annoying me and i cant bearly see enything, then i found that and english version off mhp2ndg was out and im really tempted to buy it. please can you help! i cant buy a new psp, so can you give me a cheaper way too help ( but nothing like sending it to someone, unless there in a game shop in hull ) and i would also like advise ( with reasons ) weather to save up for the english mhp2ndg ( monster hunter freedom unite ) or buy oblivion. i only get 10 pounds a weekand i already are in a months "not getting eny pocket money" as it is. p.s: white spirit is not an alcohol.
