It is never a good practice to load multiple Apps. The safest way is to load one and test to insure no interaction or problems exist that cause problems.
As suggested by fourstringfuror, now you need to delete them all and hope it clears the problem. Sometimes deleting does not fully clear an App or all it's links. You may even end up reloading the OS.
The FAQ section at the top of the forum page will have info on how to do some of this.

Good Luck.
