Hi,
I ran in the same problems. Installation ok at first and the error 00004e2e after removing the shortcut for sonic stage...
I tried to erradicate the programs and even the removing all the registery for sony and sonic... reloaded the programs under various modes... still not working and getting the same error.
After reading the hint "reformating a disc", I removed the programs with the normal windows procedure.
AND I reloded the program on an other drive (i.e. drive F:) and now everithing is working again..
Thanks to your guys
