Hi Friends
I hope everything is great there
After I had bought the Classical Guitar, I played it for a few days (maybe for only a week) and I kept the Guitar (in Tuned Condition) without playing it for about 2 - 3 months. Now, recently I took it out to start learning it, but I find that the action has slightly raised (I feel so

) and the Strings wont stay in tune !!! I tried to tune it with my Elec-Tuner too, but I feel its still not in tune.
Is it because the Strings have worn out ? Or has the Neck warped as it was kept without playing ? Is changing strings on a Classical Guitar very Difficult ? Sorry for so many questions, but I dream that I could play my Nylon-Strung (its my Fav Instrument

)
Thanks and Lots of Care to All
Your Pal
