Samples sources have been changed yesterday. Get the samples from mameworld.net/samples.

The red light: You miss something. Be sure you scan for all sets/systems.
Have a look at the mame's profile .cmp file (settings folder), open it, look out for things like:

Misc_MissingSets = 0
Misc_MissingRoms = 0
Misc_MissingBIOSRoms = 0
Misc_MissingSamples = 0
Misc_MissingDiskImages = 0
Misc_WrongSizedRoms = 0
Misc_WrongChecksums = 0
Misc_MissingNoDumps = 0
Misc_MissingCompleteNoDumpSet = 0
Misc_MissingCompleteBIOSRomsSet = 0
Misc_MissingCompleteNodumpBiosSet = 0
