Problems with different devices

Whitecamera

Hello The computer I am using is rather old and I have recently got a upgrade for it . This has presented me with two problems . Firstly The studio will not upload to my new computer , I get pages and pages of programming text instead of a upload . Secondly I cannot log into this account on my new computer although I am using same E mail and pass word . As you have probably gathered I am not Tech savvy so please explain solutions as simply as possible please . Thank you .
