PJ64 1.3 loads games, 1.4 now gives error message

[Flux]

When I try to load roms in PJ64 1.4, the following error message comes up:

PROJECT64 caused an invalid page fault in

PJ64 1.4. worked fine for a while, I don't understand. PJ64 1.3 still loads roms fine, but i'd like to get using 1.4. Any ideas?
Thanks
