FIXED IT! I had this exact problem that you guys posted and it really bothered me. I DID find a way to fix it! What i did was i went to my start menu and typed in ".minecraft" after that i hit an option that said show all items. There were over 2000 so what i did was highlight one, then held control and dragged my mouse to the bottom of my screen to highlight them all. I deleted all of these files. Then i typed in tekkit and technic and did the same. Now that i had deleted all of my minecraft files and anything associated with it, i went to re-download the technic launcher and let it update starting from scratch again. When i went to open tekkit classic this time it worked flawlessly without any errors. THIS METHOD WORKED FOR ME so if you are willing to try it i hope it works for you. If you don't feel comfortable deleting all of your minecraft files, there may be another way but i have no idea at this time. I hope this helped anyone having this issue! Your Welcome! Feel free to respond if this helped or you found an easier way.
