Try resetting your support accounts password, I check on our end and as far as I can tell you should be able to access the support panel. You can even try registering with a new email and see if the issue persists.
Are you having issues logging into the support page? Try accessing the support page directly from here -> https://www.survivalservers.com/support Your support account is separate from your website account. You can register on the support page with the same email you used to create your website account so it will link to your game server. If you don't you can always provide your username and game server ID. Then submit a support ticket detailing any additional issues you are having.
This is due to the latest patch, 85 levels are now reserved for ascension so the default of 155 levels will now only let you get to level 70 before any ascension. To get past this you will need to add additional levels to your server.
The last 75 levels are locked behind ascension. In order to get past this you need to add additional levels to your server either manually via FTP or use our Modify Server Config Tool on your control panel to add the levels!
Currently there isn't a way to do this on the control panel (this feature can be added) but until then if you want to run the experimental mode simply submit a ticket and one of our team can get it installed manually for you!
To give you some info on what exactly I did.
I took the zip you gave me and removed the BetterContinents.fwl file and had just the normal .fwl/.db file in the new zip and used our panels upload tool. As soon as it uploaded I stopped the server then using FTP I uploaded just the BetterContinents.fwl file but made sure to rename the MiddleEarthBC part to your Game Server ID number and started the server!
