Hypernova, it will reset itself at midnight, UTC - and slowly build itself up again with the successful return of Valid results. Thus, just ensure (like I think you will have done), that you'll be downloading work other than HPF2

Yes, they should be crunching again already while I am writing this. If not, force a manual project update in case some devices are on a long backoff mode.
As the quota double with every returned successfully completed** WU you should be quickly back to the max 80 jobs per thread per day, especially if you have switched to the speedy HCC project..

Knowing your setup I think the minimum quota should have been 8 for all your 8-thread machines and 12 for the 6-core ones. Probably some of them have not returned enough errors for reaching the lowest, or you now have a double 6-core that I have missed...

Edit: ** It is counted even before being actually validated.

Hypernova, after similar experiences and some research, I recommend people crunch for more than one type of WCG project at a time, but this is especially important on your i7 systems.

There are several benefits:
Obviously there is less chance of runaway failures, resulting in near death experiences (bad profiles and outages).
The overall credits tend to be slightly higher (on average) when you crunch multiple projects on the same rig.
If there are no tasks for one project you will pick up tasks from YOUR other chosen projects.

If you had been using a very low cache, you might not have had to wait so long, but when you run 2 or 3 projects there is no need to keep a very/dangerously low cache level.

It is also a good idea to check online for Errors - to catch them early.

Good luck with the other work units,
