USB booting :: Whoa! Where's my memory?

I installed DSL 2.2 on my 1GB PNY attache jumper. In a pinch I needed to transport a really big file and so I (gasp)... deleted all the DSL files. Note: I performed this butchery within Windows, now all I see available on my drive is 49MB. PNY sent me a utility to run and reformat the drive, but to no avail. How should I proceed from here? All suggestions greatly appreciated.

Boot DSL from the livecd.

Choose "USBHDD Install".

Your drive will be repartitioned correctly.
