No. Serato Scratch Live cannot currently read information from Ableton Live's warp data (.asd files).
It is not necessary to uninstall EIC 1 before installing the new version. When installing EIC 2 over a previous installation, Live will ask you whether or not it should delete the original samples.
Live can load Soundtrack loops, as they are in AIFF format. Live will not, however, make use of the specific Soundtrack loop tags.
Please be sure that the Live Set was not created with a newer version of Live. If this is the case, please update to the latest version of Live.
Live does not support split stereo files. Please save the file in another format such as stereo SDII (not split), WAV or AIFF.
Live 7 or later supports REX files. These can be loaded into audio tracks and will play at the tempo of the Set. REX files can also be sliced to a new MIDI track.
Live doesn't support DRM-protected files and this will probably not change in the near future.
The position of MIDI information like note and controller events changed when exported to MIDI files.
Live opens always with the same old Set.
