Invalid Technic Platform delivery URL

[dookleeto]

edit: ok I fixed it, I didnt realise the platform created its own url, and was using my download link instead. disregard question.

Hi there, I am trying to build my first modpack, and I have created the zip for download in the technic launcher, set up page on the site with the platform url, but whatever I try I always get the 'Invalid Technic Platform delivery URL' message.

so far I have tried:

https://dl.dropboxusercontent.com/u/26721806/mersh_0.1.zip (the 'copy public link' option from public dropbox)

https://dl.dropboxusercontent.com/u/26721806/mersh_0.1.zip?dl=1 (from a suggestion to fix link)

and from my hosting:

None of the above options worked. All of the above links start a direct download in browser without going to another page.

If anyone can help me work out what is going wrong I would appreciate it, thanks.
