I've updated the applications to version 0.09 and generated a new batch of workunits to test validation.
I believe these should both fix the low credit issue, checkpointing for the linux apps, and missing libraries on some linux hosts. I hope time estimates should be better for these as well.
I'll be checking these through the validator to see if we're having any validation issues with the new app version. Let me know if you have any issues with them.
