I don't mind having to wait a couple of days btw, happy to pay just to support, but it was something I was curious about!
Thank you for the support. Much obliged.
You shouldn't have to wait a few days with the limit for a VIP and general usage.
I'd also add, If you've already hit your limit for the day, or a close to it, buying a VIP won't help to reset the counter for that day. The VIP limit will start the next day.
I believe you should be okay now, if any further problems occur that don't fit the troubleshooting criteria mentioned by SB, then please use the "contact us" feature from the main site with the details so the developer can have a look.
