Paypal plugin problems

hopefully there’s someone that can help me out… i am working with
paypal’s web payments pro for the first time. i went through all of the
steps in the readme and basically got everything to work on my testing
computer. however once i have the files uploaded to the server, i run
the same tests, and two fail and two have errors.

/usr/local/bin/ruby -Ilib:lib
Loaded suite
Finished in 3.84531 seconds.

  1. Failure:
    test_successful_authorization(PaypalTest) [./test/paypal_test.rb:55]:
    is not true.

  2. Error:
    NoMethodError: undefined method transactionID' for #<SOAP::Mapping::Object:0xbf536dc8> ./test/paypal_test.rb:61:intest_successful_capture’

  3. Failure:
    test_successful_directcharge(PaypalTest) [./test/paypal_test.rb:48]:
    is not true.

  4. Error:
    NoMethodError: undefined method transactionID' for #<SOAP::Mapping::Object:0xbf43a794> ./test/paypal_test.rb:70:intest_successful_voiding’

7 tests, 5 assertions, 2 failures, 2 errors
rake aborted!
Command failed with status (1): [/usr/local/bin/ruby -Ilib:lib

i’m pretty sure that i have the same versions of soap4r and
http-access2 running on both machines. and since this is my first time
working with this, i honestly don’t even know where to start
troubleshooting the problem.

any help will be appreciated.
