Even if you manage to find a crack that isn't immediately flagged as malware (an increasingly rare scenario), it rarely works flawlessly. Cracks and repacks are often unstable and buggy, leading to application crashes, data corruption, or simply failing to function as intended. You cannot receive any technical support or software updates from the developer, leaving you stranded with a broken tool and no way to fix it. This is disastrous for a professional who needs reliable software to service paying customers.
