When I first tried to play PC games, I could not play them because of some DirectX issue. I did not even know about that until I had returned all my games from where I bought them out of frustration.
Google/Search DirectX and see if you have that on your computer. That is what I would have tried next if I was in your situation. Or simply search "Graphical Client error" or whatever message is displayed.
Unfortunately, it sounds like you'll probably need to involve support: firstname.lastname@example.org. Please provide as much detail as possible:
1. Confirm username (which account are you playing) 2. What area were you trying to access when this prompt to pay occurred? 3. What time (approximately) was it? 4. Please attach game logs for further review 5. Are you still having this trouble? If not, what occurred?
Instructions for sending game logs: Use your email service to add an attachment. Drill down to the Pirate101 Folder then to the Bin Folder and the Log Folder then select "Captain_XXX.Log" (the highest numbered one or the most recently dated). Then just hit send!
If this is too large for your email server to attach or send, then open the game folder, go to the the bin folder again and locate the Catpain.log. Right click on the log file and select Save as Zip (or similar wording - will vary depending on your specific operating system). Then, go back to your email and attach the newly zipped Captain.log.zip file.
