Sadly I must add that the connection problem to blitzbasic.com happens also on other pcs - not only my one
Most likely it's your ISP's DNS server that's holding on to the old IP address for the website, or possibly can't find the current DNS servers to obtain the correct IP information.
Try adding the following lines to your computers HOSTS file, and see if that makes a difference:
216.80.7.88 www.blitzmax.com
216.80.7.88 blitzmax.com
216.80.7.88 blitzbasic.com
216.80.7.88 www.blitzbasic.com
(Under Windows XP & 2000 the hosts file can be found under c:\windows\system32\drivers\etc\hosts , or c:\winnt\system32\drivers\etc\hosts
Open with notepad, add those couple of lines, and save. Should take effect immediately.
