Ok so then will I still have problems, because I only have it installed on 3 computers
No, you should not expect any. I should have said they 'may' nag - they may silently re-activate. Even if they do prompt you, yes, you have 5 concurrent activations available per OD product.
When you used the in-app 'deact all' option, you very likely deactivated PCs you didn't know were activated (newly formatted PCs, for example, look just that, new). You can always see what you have activated with this:

Something you said you did not look at prior to using the in-app deact all option.
