I checked the error report of minecraft and it says it must have lexmanos forge 1.2.2. I can provide an error report if needed. There must be a download some where.
Recently I downgraded my minecraft to 1.0.0 and installed industrial craft from they're wiki. But it won't run without the 1.2.2 version of forge. But I could not find it on the versions page. Is it still available for download?
