Black Lion Trading Company / Gem Store
I am having issues with getting the BLTC/Gem Store to load up properly. I start up the GS and times out, I restart and repeats again. The image shows as far as i can get.
Just glancing at your screenshot I would expect you to have a billing country populated in that bottom left field automatically. Maybe try manually setting one by clicking that text box that says ‘billing country’ If that doesn’t work contacting customer support is the best for personal billing issues.
You can also try clearing your GW2 cache. Instructions found via the ‘Support’ link above/below and within the Knowledge Base, ‘Search – Trading Post/Troubleshoot’.
Good luck.
