Neto, try copying all of the files with names made up of nothing but numbers (i.e. "164C549550B84211BA8C4B84AC5C0081", "63D21BEFE088433dBE3CF942347464C7") from the Testmode 2.3's "testmode" folder into Leetlauncher 3.0's "Testmode" folder. This is assuming you have 2 different SD cards, or 2 different working directories (one for TestMode 2.3, one for LeetLauncher 3) on your computer.
If that doesn't work, you might want to copy "CopyTool.exe", "MortScript.exe" and "NNTestmode.exe" from Testmode 2.3's "testmode" folder to Leetlauncher 3.0's "Testmode" folder. Then rename Leetlauncher 3.0
