Hello, I am very new to the Modding area. I wrote a Mod which gives me a cape on a special Server. Now everytime I connect my Minecraft crashes with the following Crash report: ---- Minecraft Crash Report ---- // Sorry Time: 11.02.13 15:14 Description: Ticking screen java.lang.AbstractMethodError: eg.getPlayer()Lqx; at cg.b(TcpConnection.java:466) at ayh.d(NetClientHandler.java:90) at ayk.c(GuiConnecting.java:42) at net.minecraft.client.Minecraft.l(Minecraft.java:1537) at net.minecraft.client.Minecraft.J(Minecraft.java:846) at net.minecraft.client.Minecraft.run(Minecraft.java:771) at java.lang.Thread.run(Unknown Source) A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- Head -- Stacktrace: at cg.b(TcpConnection.java:466) at ayh.d(NetClientHandler.java:90) at ayk.c(GuiConnecting.java:42) -- Affected screen -- Details: Screen name: aym Stacktrace: at net.minecraft.client.Minecraft.l(Minecraft.java:1537) at net.minecraft.client.Minecraft.J(Minecraft.java:846) at net.minecraft.client.Minecraft.run(Minecraft.java:771) at java.lang.Thread.run(Unknown Source) -- System Details -- Details: Minecraft Version: 1.4.7 Operating System: Windows NT (unknown) (amd64) version 6.2 Java Version: 1.7.0_04, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 565890272 bytes (539 MB) / 648740864 bytes (618 MB) up to 954466304 bytes (910 MB) JVM Flags: 2 total; -Xms512m -Xmx1024m AABB Pool Size: 0 (0 bytes; 0 MB) allocated, 0 (0 bytes; 0 MB) used Suspicious classes: FML and Forge are installed IntCache: cache: 0, tcache: 0, allocated: 0, tallocated: 0 FML: MCP v7.26 FML v4.7.4.520 Minecraft Forge 6.6.0.497 Optifine OptiFine_1.4.6_HD_U_C3 5 mods loaded, 5 mods active mcp [Minecraft Coder Pack] (minecraft.jar) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available FML [Forge Mod Loader] (coremods) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available Forge [Minecraft Forge] (coremods) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available craftguide [CraftGuide] (CraftGuide-1.6.5.12.zip) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available mod_ZanMinimap [mod_ZanMinimap] (ZansMinimap1.4.7.zip) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available LWJGL: 2.4.2 OpenGL: ATI Mobility Radeon HD 5400 Series GL version 4.2.11931 Compatibility Profile Context, ATI Technologies Inc.
