partial upload when Petrucci started a brief pause

[Sentle]

After filling in the initial descriptive page, when I started uploading "8 Solo Songs of 1500, mj355 (Hill, Malcolm).pdf in the normal way a message popped up saying that Petrucci was temporarily off and try in a minute. I duly tried a couple of minutes later and received an "already uploaded" message. So I then went to the "8 Solo Songs of 1500" in Malcolm Hill's page and see that 0 scores have been submitted. Similarly there was no mention of the pdf file when editing the piece's page. Please could you advise what to do. Thanks
