So im playing SK on a macbook through steam

When I try to open steam I get an error message saying something is either wrong with my connection and/or go to www.steampowered.com and troubleshoot my issues with them... Clearly my internet is working and I was on this game nearly 1-2 hours ago.... anyone else getting a similar message? can anyone give any suggestions? i cannot even log onto steam anymore without getting this message... is steam down??? HELP :)

A massage appears when i start the game: The application has failed to launch due to the following error: download.threerings.net . What is the problem? I cant play while i dont update this.

Ok I am having this problem with my Spiral Knights game. What happens is the game launchs (Via Steam) well doesnt launch the launching screen comes up after that closes the game doesnt come up. I have reinstalled the game I have restarted my computer checked my drivers everything.
Also my friend had this problem with Terraria after a quick pc restart it was working again (didnt work for me).
My game use to work for a long time now it just stopped.

Here is my Project thingy:

After patching the game up, it no longer runs. No new window pops up and I notice java closing in task manager as soon as I attempt to open spiral knights. There is no error message or any sign that spiral knights is running.

after the reboot some days earlier my night fftf disapeared from my acount karanf1.please make sure you can send hom back to my acount

This has only happened a recently but its becoming a major problem whenever i load onto a map in clockworks i always see myself just standing there in the middle of the map and everyone has run off the screen. I know this is disconnection but the wierd thing is when i stand in the middle of the screen (like you do in haven with out your sword or gun pulled) my connection meter is at full bars and whenever it recovers from the incident my connection meter turns into one bar and i begin to lag horribily. Is there a way to fix this or do i have to bear with this until i get a better computer?

The game worked fine yesterday, but today as soon as I logged in and wanted to play, the game crashes without any error message. I have tried downloading the game from here and steam. I have updated my java and my graphics drivers. I have disabled my firewall and antivirus. Please help me!

I cant figure out to uninstall the game. Can someone help?

I am trying to use the recipe for Solid Cobalt Helmet (one step up from Cobalt Helmet), but it is saying I do not have the Cobalt Helmet. Is there a way my arsenal can be checked/verified, so I can use the recipe?
