Alright, I've tried pretty much everything under the sun with this, and I'm getting ****ed off now.
Maple was fine until a few days ago, Tuesday I think. Played around for a while, closed game and had a windows pop-up saying that a file was corrupted, something about "1%" and that I should try a chkdsk to fix it. After that, when trying to start the game I'd get to the channel selection screen, choose a channel, and the game would close. After a few tries of this, the game would go to a black screen after starting the game from the website, then return straight back to the desktop and refuse to run.
That was the easy part.
Since then I've tried to reinstall the game with the v93.exe, to have it either fail or work properly. Then onto patching, where somewhere along patching the files it would encounter an error and tell me to redownload. Most of these times the error was to do with Map.wz. I tried a manual patch, same results. I then downloaded the v94.exe, attempted to install, I'd always get an error during the installation (again, most of the time with Map.wz or just after starting). I uninstalled everything and deleted files from App Data, Temp folder and even cleared my browser cache, and still the same. I got frustrated and tried a system restore, which not only made me lose the v94.exe but landed me back in the same spot. Even with what should have been a working MS folder (I restored back to the 24th), it didn't work, and wouldn't patch.
Since then I've redownloaded the v94.exe AGAIN, deleted all files, cleared temp settings, performed chkdsk at startup several times, and nothing is working. The v94.exe simply refuses to install properly. And yes, I've tried running it as an adminstrator. I don't understand how it can encounter an error during install even after removing all traces of the game and then using a freshly downloaded client installer, only for it to error on Map.wz again. It makes no sense.
I've even tried changing the file path destination, ran the v94.exe from an external HD and tried to run the installer from another HD to install it on another HD and I still get the same results.
Now the part that is interesting. I downloaded a fresh install on my desktop and tried to install on there... it still failed. I think the v94 setup file nexon has provided is corrupt.
