there is a file, Error.log, in your EFPSE installation. paste the contents of that into your bug reports and maybe we can help figure out what happened
it will probably be a while before the next update.
i am not the most knowledgeable of those here, but i check back in several times a day and i have a few months of experience with this engine. if you can post error log next time it happens i can possibly help solve it.
did you manually edit any dat files? or change the name of any image file? these errors are usually the result of efpse not being able to find something because it's not there anymore. there are some methods for manually debugging that i can share.
dont give up. it can be very frustrating trying to figure out the intricacies of the engine but some very good games have already been made using it in it's current state.
