Exit the game close the launcher. Wait a few seconds and restart the game. This can "fix"it. There should be a patch coming soon. I believe this is going to be one of the fixes, but I could be wrong.
Unable to buy a module
I have the same problems since yesterday. I mean, i need 10 minutes and 10 clicks to get access to the game and than i cannot buy any upgrades. Everytime it shows me -1 credits.
Same problem. I guess the servers are kinda broken due to the masses of new players...like me.
edit: Suddenly there was a correct price, I was able to buy it...the game kept loading...and loading...and loading...then I lost connection. I relogged and now it is like before: -1 and not able to buy it.
P.s. I also did not get any exp for the last match.
To be fair...since a a few hours later everything works now and is stable. Thumbs up
