Title: I can not reupdate Tekkit Version: 3.1.1 OS: Windows 7 Java Version: Java 7 Description of Problem: I have recently downgraded my tekkit to get onto a different server than usual. After the update, all was fine, until i wanted to go back to my old (new) version of tekkit. it wouldn't let me upgrade it or even downgrade it again, I couldn't even clear the caches, which i thought might work.
