OP, the reason why you are having such problems is because something keeps touching inside the client folder, could be due to your tweaks, could be due to your third party programs (famously like anti-virus) that likes to snoop around and delete practically anything that's downloaded over internet.
@Lapsap
Your post indicates you are having intermediate problems with launching client. Our launcher is heavily customized, It is very diligent as it performs many critical functions that invokes proper playing condition.
The very first thing you should do is try by doing a
'Version Check' this will ensure your launcher and client are the latest available offering, as older ones may not function properly or do not have capabilities to play.
1. Locate PirateKingOnlineLauncher.exe and execute as Administrator. Right-Click on PirateKingOnlineLauncher.exe and click "Run as Administrator". PirateKingOnlineLauncher.exe is located in main client folder, or you may have a short cut to PirateKingOnlineLauncher.exe on desktop.
2. After the client launcher is launched, Begin Version Check by clicking on button at top left corner, Where a drop menu will appear with choice of "Version Check" in the top of list.
3. The launcher will automatically quickly scan your client files and begin to download any missing or malformed client files.
At this point, If you are still unable to play, It means that you have a service or program that is actively blocking the connection such as firewall or anti-virus.
1. Unfortunately because there is too many anti-virus and firewall solutions there is no easy way of turning them off, You will need to contact your antivirus/firewall company to ask them how to remove/stop.
2. In very rare condition, You may have a ISP that does internet filtering which means you most likely cannot play because ISP do not remove or allow you to circumvent this filtering.
