This is mess. OP is not updated and there are mixed links all over the place.

For the record:
Current official page AFAICT is https://fastcoin-project.com/index.html
Block explorer with list of nodes: https://chainz.cryptoid.info/fst/#!crypto
Source code/project (has also working Windows binary): https://github.com/fastcoin-project/fastcoin
Bootstrap: https://drive.google.com/drive/folders/1bnXXo0EGV3iAY_x8hu3Rpv6SirSoS-pW

Note: It appears there was change to netcode/block store, so older wallets can't connect or use bootstraps.
