I made the mistake of upgrading eclipse today and now can\'t get my a new Android project to get going.
I get the message Proguard.cfg (the file can\'t be found).
I just experienced the same problem.
You need to update your SDK tools to current version.
In Eclipse go into your Android SDK and AVD Manager. Select Installed Packages in the left hand tab. Click Update All. Select the SDK tools latest version. Click Install.
After it's done you should have the Proguard.cfg file in your tools/lib/ directory.
