First of all, let me say that this method assumes you have only one bad plugin that is causing trouble and that your test when you installed it didn't find the problem and you accepted it not knowing that there would be trouble later. Start: Save your entire plugins folder to some safe folder. Divide your plugins into approximately two equal halves. Put one of the halves into your Plugins folder Test the game, thoroughly to provoke the problem If the problem does not occur, this set is safe. It remains in your plugins folder. If not swap the two halves and test again. If this set is OK, it becomes your first safe set and stays in the plugins folder. If not, you are outside this algorithm because you have more than one bad plugin. You will have to seek other solutions. Point X: From this point we assume that you have a safe set of plugins in the Plugins folder and the remaining set elsewhere. Divide the remaining set into halves. Put one of them in the Plugins folder being sure you can get them out easily (use a folder) Test the game. If all is well, go to Point X: If this set now fails, remove the last set and replace it with the other half. Test again. This should be OK, but if not, you have more than one problem, so exit. Otherwise go to Point X: Continue dividing until you have a set of only one plugin that tests bad. This is the culprit. You can then restore your saved plugins suite, and remove the guilty party. End:
