Running Windows 7
Previously installed Reader 9.4 and it worked for a few days. Stopped working, uninstalled and reinstalled (twice). I try to open a file using Adobe Reader and the only message I get is "Internal Error" and the program has to close. No error number is given. Help, I need to do my math homework from a cd or the website and they both need Reader......
