In this situation, just keep in mind that if something goes wrong, it's not your fault. Do the best you can with the training you've received. You can use your creativity and pro-active skills but you can't work miracles.

Here's a personal story that might help: many years ago in the beginning of my career I was assigned to install a software client on various machines (about 50 workstations), using a CD. It was a Friday, worked until late but had to leave to continue next day (Saturday!!). When I arrived I noticed the CD was cracked. Either me or the cleaners accidentally put something on it. I then called the IT admin (who was on a holiday) and told him the CD was cracked, I needed another one. He said we didn't have it. I then called the software supplier (Sybase Inc) to ask about a replacement media. Obviously we had the licence, it was just a matter of getting the binaries, right? Wrong, they said we had to purchase a new licence. I then tought I should pay for it since I felt responsible for the damage. The price was really high (can't remember, something like x thousand dollars - I would have to work for many years to pay that with my junior salary). I tried finding people around and on the internet with the same software version so I could clone their CD but there were too many minor releases and none matched the same as our licence. This is Monday already and I had no choice but tell the boss what happened (over the phone). She asked how much it was, I told her. After the longest 5 seconds of silence she said "OK, it was not your fault, we should have made backups. And we were outdated anyway, it was time to upgrade, please tell the finance I authorise the purchase and tell them to invoice us". Phew! Many lessons learned on that weekend.
