Please download and reinstall the latest version 4.0.2.1. This is a new wallet from the recently released v4.0.1.1. You Must update to be on the correct chain. This will finalize the NLC2 fork.

This release fixes client versioning as displayed in RPC results, removes some compiled mining code to reduce false positives for mine-ware, adds 8 new seednodes, and checkpoints the foundation postmine to help with network partitioning that arose from too few users updating before the postmine transaction
