Adobe "Send in Bulk" feature keeps timing out.

[Landon24338072nz1s]

I'm trying to send a policy to everyone in the company using Adobe send in bulk feature. It only let me send 50 at a time, so for a company with 250 employees I  will do it 5 times. That's ok, not bad. I did it four times and now when I upload the last batch, choose the file and hit next, I just get an endless spinning ball on the screen. I've tried it 5 times already, closed the program, reset my computer. Nothing seems to be working. Is there a problem with Adobe sign in bulk?
