Just Donated but Firmware downloads failed and used up credits

I have just donated and tried to download Ender3-v4.2.7-BLTouch-20241018.bin file 4 times and each time it failed. That has used up 4 credits, and I am without the file. Can you help please and re install my credits. Thanks for your help

I think you might be a bit confused at how credits work.

They are only used for successful builds of firmware via the custom builder. Nightly builds do not use credits at all.
