Hi Phree,
This error is generaly showed if have a corrupted file on DAoC Client or DAoC Portal.
1. test to put
libxml2.dll file on DAoC Portal folder and DAoC Client folder.
2. If not works, uninstall DAoC Portal, delete C:\Users\Phree\AppData\Roaming\DAoC Portal folder. Reinstall it.
3. If not works again, delete and recopy a fresh client copy.
4. If you don't have a fresh copy or if not works again,
redownload it by beginning.
I hope will fix your problem.
