Windows XP/Vista/7 some Keyboard keys stop working once i open maple

hello lately i got a problem with the game.

since two days ago everytime time i open the game my whole keyboard gets weird.
when i open maple my top keys stop responding, it only affectes my number keys and page down and even after closing maple it takes from a few min up to a few hours until the start responding again. i have been trying a few things and it only starts once i open maplelegends.

can somebody help me its getting really anoying and i cant find a way to fix it :S

 

update:
once its bugged does keys wont get unstuck from restart or reinstalling from keyboard programm
after 30+mins of constandly pressing all kinds of buttons with those numbers, they start responding
but the moment i go back in game they get stuck again.

also checked if my keyboard has a problem but after hours of writing and watching movies all keys are still responding
soo i guess it should be fine.

 

my keyboard language is active, and i can freely switch between mine and eng, but keys are still stuck

 

okay gave it some more testing
after closing maple is usully stay stuck but if i conect and unconnect another keyboard
while also spamming ctrl+fn+alt+shift+cap + stuck key than they get unstuck after a while.

alsooo the bugg only happens on my current laptop keyboard if its connected to my other keyboard it works fine.

ps before some ask it feels really strange to play it with another keyboard.
and since the other keyboard isnt broken i would prefer to continue playing with my laptop keyboard

 

nooo turned off stick key a loong time ago

edit: also checked its still off

 

nooo its not num lock, also some keys from num block are also stuck.

 

im using window modus

not sure about legends+ but i just downloaded the regular version and used it ever since

and no only maple legends give me the issue

edit: also the game ran fine for almost a whole year
and suddenly it happend a few days ago

edit 2: i also though if maybe a windows update caused a error and rolled my pc back but it didnt fix the problem

 

im using a lenovo G580

and yes once they are stuck they dont respond at all no matter where i try to type them.

and only random button mashing outside of maple get them unstuck....
also tried other methodes like restart and keyboard software reinstallment beforehand but does didnt do anything.

 

sooo tried virtuel keyboard and it responds, i also tried usb keyboard and it also responds.

i checked my setting and i looked up power drain, but it didnt work

alsooo i dont think there is a problem with the keyboard connection since it works fine everywhere else
