"Not in Range"

Character Name: Wolfgang Takeo
World: Zalera
All classes are affected (namely melee)

So, I have some sort of issue/bug/glitch, ever since this last patch, where I keep getting the error message, "Not In Range," despite clearly being in range. I will even get 2 parts of a combo off and, without me or the enemy moving position, then all of a sudden get that message. Even when i am moving my character INSIDE the enemy character sprite, I am not in range. I can't play the game, as I can't do dungeons or instances for I cannot do damage/combos. My internet and computer is high tier and have never had a connection problem, even after double checking. I'm a long time player and haven't encountered anything like this, where despite my distance, I am just "Not in Range." I literally cannot progress anything within the game due to this issue. I have replaced keyboards, mice, etc. The issue remains, therefore I can only conclude it's a problem not on my end. It has been more than a week since I reached out to SE and only recently got an email saying to post my problem here. A bit upset, as I am at a point where I am paying for a game I cannot play. Please help me out to figure what is going on. If it IS on my end, how to fix, and if it isn't, to just have fixed. Thank you

Maybe your character needs glasses? ;P

Joking aside, did you check if you have the "automatically face target" option on? If you're not facing the target properly it will not register the hit. I notice that most when I switched it off for healing certain fights and forgot to turn it back on for dps.
