If you experience problems running HFSLIP and you're sure you closely followed the Basic how-to guide, first check on the HFSLIP support forum if your problem wasn't discussed before. If still no luck, please start a new thread on the forum and attach a ZIP package containing HFSLIP.LOG (created by HFSLIP).
If the problem manifests itself after installing the updated Windows source on a computer, also include a file named WUx.TXT in the same ZIP package.
How to create WUx.TXT:
This will create a file named WUx.TXT ("x" is a number which will increase as you run the application again).
If of relevance, you may also include logs from other tools with more information about the problem.
