Hello to you all.

I have an Acer Aspire E15 with Windows 8.1. My keyboard is in english but since I'm from Venezuela I use the English International keyboard so I can type accented letters. It was working fine until yesterday when the quote mark, tilde and apostrophe stopped working. I have to press the key for about 10 seconds for it to work, but still it doesn't help very much since I can't type accented letters. I switched the language to English US and the keys work perfectly, so I'm guessing it's not a hardware problem. Can someone help me please? This is crucial to me

Thank you very much.
