Epic Privacy Browser Forums

I've been using Epic for a few years on my Asus windows 7 pro computer. It disappeared. Icon still on taskbar but click on it up comes an alert that says epic.exe file is moved or deleted so icon won't work and asks if I want to delete shortcut. Read other posts here and uninstalled it. I also tried to delete Epic privacy browser folder to no avail, alert comes up saying it can't be deleted because one of the files is being use by another application. Anyways, downloaded it again and ran installer. After a couple of failed attempts finally it installed and put shortcut/icon back on taskbar. Epic opened automatically but almost immediately shut down. Clicked icon and got same message as before about being moved/deleted. Went to control panel home programs/features to uninstall it and try download again but it wasn't there. After few more tries it showed up on list of programs but deleted on its own.  I really like using Epic and want to get it back working on my computer. Help will be greatly appreciated.

Sorry for the long winded post.
