42 coin wallet issue

[swagkiller69]

Hi guys, I'm not sure if this is the correct place for this but I looked around and couldn't find anything closer
I built my wallet using this https://github.com/fourtytwo42/42
and have tried deleting everything and rebuilding and letting it redownload and both times it gets stuck at block 990381
I searched google for this and only one other person has posted around this and he never posted about it again after and nobody offered a solution, any ideas anyone?
Thanks in advance
I also have this error

"errors" : "WARNING: Displayed transactions may not be correct!  You may need to upgrade, or other nodes may need to upgrade."
