List Fortress - list upload problem

I hosted an X-Wing event.
I have problem with uploading lists to List Fortress.

I successfully submitted the event.
After that, I successfully added players.
Then I started uploading the lists.

My first problem was that even though I pasted a YASB link, the list didn’t appear.
I tried pasting an LBN link, and that worked.

After uploading 5 lists that day, I stopped, thinking I’d continue the next day.
The next day, even though I inserted the LBN links, the lists wouldn’t appear.
And they haven’t since then.

I’ve encountered the following related issues:

• the YASB xws import into LBN fails,
• when I paste a link imported from LBN into a web browser, I get an error message.

So, I’m asking for help: currently how can I upload lists to List Fortress?
