Netherrealm Studios just published a fix to deal with the online de-sync issues with the Klassic Kostumes on
XBox 360. Follow these few steps:
The steps to redownload the retro skins are as follows:
1. Hit the guide button (XBox Logo button on controller)
2. Go to the right to the tab labelled "Settings"
3. Select "Account Management"
4. Select "Download History"
5. Select the pre-order DLC you wish to re-download.
6. Choose "download again"
Repeat this for each skin that you have downloaded. Fix is still in the works for PS3.
