Decompile existing legacy .NET code to remove a limitation

We need a change made to some legacy .NET code that we no longer have the source to. The change involves disassembling the .NET assembly to remove a limitation in the software. The limitation in the software is 2 or 3 lines of code that checks a standard serial number. We need to remove this limitation to work around these lines of code. Rules: 1. You bid on the project. 2. We send you the Windows software in question. 3. You alter the software and produce a workaround. 4. You send us a screenshot proving the software is working. 5. We will immediately pay you $200 and award the project to you. We WILL IMMEDIATELY PAY $200 and award the project to the first person that can prove that they have a workaround. A screenshot showing the software in operation will be sufficient. Note that we WILL NOT award the project to anyone unless they demonstrate that they already have the fix.
