I have been playing on the same computer for about 5 years and it worked perfectly. Now for some reason i can not jump while running woth sprint or just at all walking and jumping. I try to do it and i just jump in place. I tried changing version and it did not work. I try to run and jump and it goes well for about 1 or half a second and then i jump in place with no movement at all for like 5 seconds and that has been happening for about 2 weeks now. On all servers. I didnt change anything in my computer, version or buttons. It just started happening out of nowhere. What do i do? Sorry for mistakes, English is not my main language.
