Hello and thank you for reading this. I just added AE (applied energistics) to my forge client (1.7.2). When I start my client with AE it crashes. I thought that all I had to do was remove AE but when I did forge stopped my client from loading because the AE file is no longer there. I have a screenshot and the crash report below.
