I have consistent failures with Adobe driven links. When they come up my computer malfunctions and I must reboot. When I do that I get an update notice from Adobe that stalls my computer while it runs and when it finally get done it gives me a message saying my password is already taken and.
Then, I reboot and start over and ignore all Adobe based programs once again.
Ad Block is your best defense against Adobe silliness. Unless you actually need to load Flash. Sometimes uninstalling Flash and putting it back helps, sometimes.
Using Firefox allows the use of No-Script which prevents the nonsense from starting. It does take getting used too, but it’s worth it.
