Ha, this happened to me and I circumvented this by switching my plan to a new plan which kicked off some trial grace period, at which point I cancelled my entire plan. No cancellation fee.

Curious, what did you choose as a replacement for raster graphics? GIMP is a no-go, as its slow and buggy as well.
Raster graphics - Affinity and an older Mac with Photoshop CS something :D
It has been a good replacement for my limited needs, give the free trial a go and see if it has all the features you want.
As a bonus it is also super cheap compared to photoshop. A permanent license right now is only $25.
I use it in combination with Capture One, but if Serif ever release a tool that can manage my ~30k photos I'll definitely consider switching.
