Here's what happens when I try to download the fishing boat from Kenichiro:
09:56:25 AM - Starting Trainz Helper (v2.4 build 2365)

09:58:30 AM - Download of CDP package failed.
Also, before this happened, when I downloaded something, CMP opened, since I have TRS2004 and TRS2006. Then when I started the download, an orange bar appeared at the bottom that said the item was unable to be downloaded because the server was too full. It said this every time I used CMP. I think the reason CMP opened is because I hadn't updated the TRS2004 download helper, and I had also recently changed my password, so I retyped my password in the login details on the download helper for TRS2004. Then when I did, the text in red above is what appeared in the overall progress.
