For the users experiencing problems with cam-x, make sure you have downloaded the LATEST version from the downloads section, make sure you have the LATEST verson of the Java Virtual Machine installed, you can look this up on Google. Once you have these steps done, open cam-x, press the update button, restart cam-x, and then you should be able to login.
Press update to update your Cam-X, you don’t have to redownload the entire program again.
Cam-X is fixed. Redownload it and it should work.
