I run on 32-bit windows 7.
My friends want me to play Minecraft on a server they run with the newest updates (meaning I need to replace the .jar file). Last week I created my screen name, played around a bit on the old classic free minecraft from the website. I also downloaded the launcher for the paid game before I purchased. After I made my purchase, I attempted to log in on the launcher. I get a grey screen and this error:
((Click here for screenshot.))
<html><body><font color="#808080"><br><br><br><br><br><br><br><center>Failed to update news<br>java.net.ConnectException: Connection refused: connect</center></font></body></html>
When I attempt to login, I get the message:
Can't connect to minecraft.net
((Another screenshot here.))
Okay, that sucks but I suppose I can try the browser. Now, the browser WORKS.
When I attempt to join that server, it says my version is outdated. This is to be expected. They are all playing on the new official 1.9 beta release minecraft.jar file.
However, when I replace the.jar file with ANY other minecraft.jar file than the one downloaded from the minecraft.net browser, the following happens when opening browser Minecraft:
1. I see the 'downloading' screen for a split second.
2. The browser minecraft screen goes black.
3. Mozilla firefox freezes for a few seconds (or freezes completely)
4. The game crashes.
(Or I assume it does, it glitches out by showing any other window I minimize from and is unfunctional.)
Edit Update: Java Console shows this when I attempt to run 1.9.5 after Mcpatcher in the browser version:
Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission getenv.APPDATA)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.System.getenv(Unknown Source)
... 5 more
Things I have tried to do to fix this:
-As suggested on the IRC, I have allowed filters/disabled firewalls.
-Disabled popup blockers in my browsers.
-attempted to reinstall Minecraft completely after wiping all Minecraft data.
-attempted to run after a complete reinstall on a completely new browser. (Opera)
-attempted to download a new launcher from another site.
None of these things I have tried to do has helped or fixed the problems.
A the moment I am only able to play on the browser, and only with the .jar file provided with the 1.8 download on minecraft.net. Until I can change the .jar file, I am unable to play Minecraft for the very reason I purchased it.
=The only suggested thing I have not done is open a port on my router, which I was told is only needed for servers, but I'm willing to do if I know what port needs to be opened and it may help.=
ANY help with this would be GREATLY appreciated.
Edit: I'm able to run 1.9 now, though only because of the update provided through the browser on the minecraft website. other modifications to the .jar file cause errors seemingly.
