Check Pairing Integrity

If you have trouble entering results for a particular pairing, then it is possible that somehow your SwissSys file has become corrupted. If you type a “W” to give a player a win, for instance, and nothing at all happens, the program is having trouble reconciling conflicting information somewhere along the line. To remedy this situation, go to the pair chart and select Tools | Check integrity. SwissSys will then look for errors in the pairing and correct them.

In all but the most extreme cases of data corruption you should then be able to proceed normally.
