Was just going ask that myself, can anyone update the v2.0.0.0 wallet past block 509386? It stops dead there for me, with 5-6 connections active.
This GLX Pool working on block 509,775 currently, far away of 509,386, so I suppose there is no evidences for network sync issues.
Should your wallet continue nor syncing, consider to add some active nodes to galaxycoin.conf configure file. Here is my wallet's connections:
