[317] Sorry, an error occured whilist loading

Hey Guys! Been a while since i’ve posted here.
Anyways, I’m running into a bit of a Client problem… I have the cache in the right place, the cache name is also right, the IP is set and everything is the way it’s supposed to be. Yesterday, I was running the Client i’m working on and everything was working perfectly fine on my Mac.
Then, I transfer the files over to my Windows PC and put the cache in right place and checked to see if everything was in order, which it was… Then when I tried to run it, it gives me this error: "Sorry, an error occured whilist loading"
I have attached a screenshot of the Client for viewing.
Here’s what the CMD reads:

java.io.FileNotFoundException: C:\Users\mamali t\OwnXileHD\sprites2.idx (The sys tem cannot find the file specified) at java.io.RandomAccessFile.open(Native Method) at java.io.RandomAccessFile.<init>(Unknown Source) at java.io.RandomAccessFile.<init>(Unknown Source) at DataUtils.readFile(DataUtils.java:99) at SpriteLoader2.loadSprites(SpriteLoader2.java:16) at Client.startUp(Client.java:8799) at RSApplet.run(RSApplet.java:117) at Client.run(Client.java:5868) at java.lang.Thread.run(Unknown Source) java.io.FileNotFoundException: C:\Users\mamali t\OwnXileHD\sprites2.dat (The sys tem cannot find the file specified) at java.io.RandomAccessFile.open(Native Method) at java.io.RandomAccessFile.<init>(Unknown Source) at java.io.RandomAccessFile.<init>(Unknown Source) at DataUtils.readFile(DataUtils.java:99) at SpriteLoader2.loadSprites(SpriteLoader2.java:18) at Client.startUp(Client.java:8799) at RSApplet.run(RSApplet.java:117) at Client.run(Client.java:5868) at java.lang.Thread.run(Unknown Source) java.lang.NullPointerException at java.io.ByteArrayInputStream.<init>(Unknown Source) at SpriteLoader2.loadSprites(SpriteLoader2.java:20) at Client.startUp(Client.java:8799) at RSApplet.run(RSApplet.java:117) at Client.run(Client.java:5868) at java.lang.Thread.run(Unknown Source) Map Amount: 1226 6561 java.lang.NullPointerException at RSInterface.addAdvancedSprite(RSInterface.java:280) at RSInterface.bountyHunter(RSInterface.java:310) at RSInterface.unpack(RSInterface.java:261) at Client.startUp(Client.java:8924) at RSApplet.run(RSApplet.java:117) at Client.run(Client.java:5868) at java.lang.Thread.run(Unknown Source) Error: loaderror Unpacking interfaces 95
Any and every bit of help is much appreciated!
