Renesis is dead, it was either a scam or a failed project.
I don't know about Maplechange but with such growing competition among the exchanges, I didn't expect a small and amateurish exchange like Maple to stay around for long. I hope all you had there were just RESS coins which aren't worth anything anyway.

As I've stated above, if you're looking for alternatives to an anti-ASIC coin then go to Ravencoin or even better to XDNA which is both ASIC and FPGA resistant and it's also focused on supporting scientists, charity and overall improving the world.

Just so you know, Ravencoin can be mined with FPGAs, though it seems it's not a mainstream solution yet.
