it takes some time to load the first time, please check if you can find the process "Terminal.exe" in the Task manager>Processes.
Yup,its there,but it still wont open.. This is a really big problem for me because I cant trade without MT4.
can you say anything about when it started?
did you accidentally load a faulty indicator or expert that made the terminal enter an endless loop ?
if so, then it will try to load this faulty indicator or expert upon rebooting the terminal the only solution would be to rename the file name of the ea so the terminal can not find it anymore and thus can not load it upun booting the terminal.
What OS do you have? Try to find data folder and rename default profile to test profile. Also write post to the ServiceDesk with all logs.
