Having insufficient RAM available has been known to cause textures not to load. Your resource pack is increasing the texture size by a factor of 4, so it is not unreasonable to assume that you would need more than the recommend 2 GB to use your resource pack. If you aren't able to do this yourself, then perhaps you should give it to someone else to see if it works with more RAM.
