PortableApps Corrupted and Start EXE Deleted

My computer ended up putting a fake error on my usb which ended up closing all the apps and the platform itself. I then tried to relaunch the platform but it would not launch. Then I tried upgrading it with the installer, which also did not work. I then tried to do it again, but deleting the Start EXE beforehand but now the updater won't even recognize it as a usb with PortableApps installed. Now, I'm stuck with all my data unrecoverable. Please help.
