When I set my buffer size to 128, the session samples start to crack and drop out which is annoying

but if I set my buffer size to 256 it doesn't drop out but there is a slight noticeable latency when recording my guitar.
Is there a way around. I've tired almost all the method but to no avail. Any help will be appreciated.
You have already discovered how increasing your sample buffer improves audio reliability at the cost of some additional latency.
The cheapest, easiest workaround is to leave your sample buffer adequately high and use direct monitoring while tracking instead of monitoring through your DAW. I haven't used your interface before, but I'm guessing the "D/M" switch on the front panel is for direct monitoring your inputs? You will also need to make sure to set your track monitoring to OFF on the track you're recording- if you don't do this, not only will you hear phasing while your DAW audio mixes with the interface audio, but Live won't do any latency compensation on the recorded track, guaranteeing that it's out of sync on playback.
The only problem with this is that if you are the type of guitarist (or vocalist) who likes to hear effects on your playing/singing while recording, you can't do that while direct monitoring unless your interface is equipped with built-in DSP effects. If you need to be able to hear effects while you track (and your interface doesn't have built-in DSP), then you might look into upgrading to a faster computer and/or an interface with better low-latency performance. For USB interfaces, no other manufacturer is even close to RME, but Steinberg and MOTU both offer better-than-average USB performance.
EDIT: Also, the driver error compensation thing is different from just regular latency compensation. Live has a built-in tutorial that walks you through setting the correct error compensation value, but it will normally be a very small number, and will not address the problem that you're talking about.
