Jeff, since we sent you the username-password 3 times and they never worked for you, and MTUSUPPORT verified what you sent him works fine, then the problem is on your end and there is nothing we can do to help. Find another email ISP vendor, or remove the blocking software preventing you from logging in! We have seen this elsewhere in Europe once before.
MTUSUPPORT emailed the Microeditor 5.3 code directly to you to solve your sign-on problem. We have not heard back from you whether this solved your problem or not.
As we indicated last year, the new DNoise V3.0 is a DirectX plug-in that requires a "directx platform program" to run in. We understand that you chose not to download any other directx enabled editor demo. Now that you have Microeditor 5.3, you should be fully able to run DNoise V3.0.
Let us know if you have any other problems.
