Chissà... l'ultimo fix dei crimson non risolve, qui dicono:

First, do not use Crimson. It doesn't work. I've talked extensively, and in detail, over at overclock.net about the problems it causes. Btw, it doesn't uninstall properly either so it conflicts with just about everything. Uninstall with DDU and then run CCleaners registry tool. Afterwards, manually remove the registry entries that will reappear after reboot (because try will reappear along with the folders and the exe)
