First, if game crashes a lot, try Game-Ranger connection instead of Hamachi.
Second, I would like Dwarves (or Chaos D) to have xbowen and give the Handgunners to Empire (or those in a horse, like Pistoliers). The true is that Chaos Dwarves are too expensive, so a cheaper range regiment is not bad seen (expensive catapult and some "cheaper" xbowen... 750gc instead of 900gc?)

Giving crossbows to the normal Dwarves and handguns to empire is a good solution. It have the added benefit of making dwarves and chaos dwarves more different.
The chaos dwarves gunnes got higher bs and cause panic. In my experience they are very dangerous and worthy of their high cost. Does anybody else got an opionon on this? Also remember that the Chaos Dwarves can recruit cheap goblins (an option that normal dwarves don't got).
Dwarves are currently considered to be an above average race on the par with elves. Compared to halberdiers (the standard 450 unit) they got 1 less m and I but 1 extra armour, WS, T, and 2 ekstra LD. If they preform badly I would think that a better solution is increasing the size of their unit.
