What a tiring...

...and frustrating time the past two weeks had been. I had been trying to set up a testing environment similar to that of a client. But no matter how many times I install the client's software and test packages, or how I tried to mimic the configuration of the client's, even close to the point of transplanting everything, just short of taking over the client's computers. I already don't know what else I can do now. So disheartening and feel like giving up. But I don't want to give up...
