I do not understand the message you received, as there is no time limit for withdrawing payouts. Indeed, you do not have to withdraw them at all, leave the accumulate and eBay will send them to your nominated bank account selected for Managed Payments every 3 months.
You could try Customer Services explain the tech issue you had with your laptop when entering a new username ID ( why did you change this?) and see if they can help you now enter your bank details. It will still take a few days to verify new details.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open for ' live agents' 8 a.m. - 10 p.m. on weekdays

Automated agents will be available on chat outside of the above hours.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
