2 days ago I was trying to use
this version (R2B46d fullpack) with the newest metamod 1.19.p28 and it was working without any crash 1h on windows listenserver and 1h on windows dedicated server (I haven't had time to test it longer, but I didn't experience any crash during my tests). If You installed metamod 1.19p28, then you installed ALL in One package, it overwrote Your newest metamod. Then - if You downloaded and installed AMX X1.70 - it started with incorrect version of metamod (because - probably that Your newest one has been overwritten by All In One installer) - so probably because of this You are experiencing crashes.
Explain more detailed what do you really want to get to work - which plugins, then I may write more detailed description for You, how to install it.
