That did not fix the problem. What IP does ckrenbre.x10hosting.com resolve to for you? For me it resolves to 74.86.117.240. I cannot ping it, access it from http, cannot log into cpanel, and I get invalid password when I try to log into my account from http://www.x10hosting.com.
NOTE: Your instructions for flushing the dns cache are incorrect. The command in Leopard (I have 10.5.3, the latest update) is:
dscacheutil -flushcache
not
dnscacheutil -flushcache
Edit:
It's working now, thanks!
