No need to apologize, everybody has been new to this at one point.
So it did not allow you to install it? Wow that is weird. Thought for sure that it would work.
There is another way but it would void the warranty (however, it would be possible to revert to stock).
It is a little bit risky, there have been a couple of instances where I have heard of it not going right and ruining the phone but I (as well as many other people) have done it many times with zero problems (if you just follow the directions carefully you should be fine). It does not root the device but does install firmware from a different region.
Just download the .bin file from here-
Acer Liquid and Liquid E ALL ROMs bin extract collection - Android @ MoDaCo (I'd reccomend 4.002.14.EMEA.GEN1 or 4.008.08.EMEA.VFIT)
And follow these directions-

And if anything goes wrong, refer to this thread-
