i don't have Xfer folder ... how to have it

i don't have Xfer folder so i can not add presets in to serum

how can i have it back ???

are you sure you do not have a Serum Presets folder? Serum won't run without a Serum Presets folder. Menu->Show Serum Presets Folder.

If you are missing a Serum Presets folder, Install 1.0 which is the lowest download in "your account" just for the presets.
