as you can see, i have the watir gem installed but cannot load it in  
irb. dont know how to troubleshoot this.

U:\\>irb  
irb(main):001:0\> require 'watir'  
LoadError: no such file to load -- watir  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):1:in `require'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):1  
irb(main):002:0\> exit

U:\\>gem list --local watir

\*\*\* LOCAL GEMS \*\*\*

watir (1.6.6)

U:\\>ruby -v  
ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]

U:\\>irb  
irb(main):001:0\> require 'watir'  
LoadError: no such file to load -- watir  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):1:in `require'

i made it to work by loading rubygems first.

U:\\>irb  
irb(main):001:0\> require 'watir'  
LoadError: no such file to load -- watir  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):1:in `require'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):1  
irb(main):002:0\> require 'rubygems'  
=\> true  
irb(main):003:0\> require 'watir'  
=\> true  
irb(main):004:0\>

However, i never had to load rubygems before. the script i am running  
was working before i reimaged my machine and reloaded ruby. what did i  
miss in my install that i have to require 'rubygems' now.

Perhaps your old system had the following environment variable:  
RUBYOPT=rubygems setup.

RubyInstaller no longer adds RUBYOPT

See above, I showed you what RUBYOPT should be set to.
