Cannot send invoice or send email to support – Hours Keeper Pro - Timesheet, Tracking & Billing Review

I used to use ours keeper and haven’t used it for a while and recently started to try to do some billing again. I have an invoice that I simply cannot send. The send word is grayed out. Nor can I send an email to app support for the same reason. So then I got ours keeper pro thinking that would make a difference and it makes no difference at all. I cannot get in touch with the app people for any kind of support and I’m very frustrated especially now that I’ve paid to have pro. I sent an email from my regular email to what I think is a support email address but have received no response.
