The deadline to register for a peer-reviewed computer science conference with proceedings is in three days and I cannot attend despite being the main author of a paper there since I am leaving the current institution for non-academic employment. I cannot afford to lose this job and losing it will have catastrophic consequences. I have discussed this issue with the coauthor for many months, and they kept saying "I'm pretty sure that I can go, but if not we'll find a solution". At least one author of the paper must be registered and at least that person must present it at the conference or else the paper will not be published.
There has been still no tangible proof of the coauthor either definitely going to the conference or registering, and I do not know this person well enough to trust them. The publication is critical as it is the only proof of me producing anything in quite a long time, so I cannot afford to lose this publication. I cannot take the stress any more. How do I ensure that someone registers for my paper so that it appears in the proceedings?
