When running DigaGrabber 1.0 on Windows 7 it could happen that connecting an external drive while there is also an internal drive could cause a problem in DigaGrabber by not finding the drives. It will present a list of CD drives but it is impossible to use one of those devices.
This problem is caused by an old version of wnaspi32.dll which is developed by Nero.

To fix the problem the file should be updated to which can be downloaded here: ftp://ftp6.nero.com/wnaspi32.dll
Please ensure that you are using at least akrip.dll 1.1r4 and DigaGrabber.exe
