Problem: Any number of different problems
Solution: Be sure that there are no other programs running when you install the PageGate GUI Client. There may be programs running even if you don't see them in your task bar. Pressing <ctrl><alt><del> will bring up a list of running programs in the 'Task Manager'. Stop any program that you believe is causing the conflict.
WARNING: this should only be done by an experienced user. Randomly ending tasks can lock up your computer, lose data or worse. Please consult with and experienced technician before killing any processes. A clean reboot can sometimes also help. Holding down the shift key while windows is starting will stop some programs from starting that normally load at startup. Try re-running the PageGate GUI Client setup program.
