Can't import BOS file from the same version

I have been trying to import a BOS file from a project that was exported in the same day from the same PC and now it says:
"Designed with a Subscription edition. Incompatible with Community edition"
I never had a subscription edition, I installed bonita last week so no update was made
I am using bonita 7.8.0

Uploading a bos file from the portal


I'm following along with the getting started tutorial (Travel Requests) and I am at the part where it says to export the project from within bonita studio and then upload it as a resource in the portal. However when I go to resources in the coolbar and click add, it only allows me to upload zip files. Whats up with that?

Extract java code

Is there any way to extract the entire code that makes a .bos file?
