I wanna uninstall it because no one plays it and it might cause problems and I can't use /arrows with it and there are some sprite issues with it, like worms jumping just a tiny bit, but a little annoying.

Thanks.

Just delete all PX related .dll files, should be enough. Cant remember filenames, wkPX.dll and the other one. You will find them in your main game's directory.

I can't use /arrows with it
I can. Just run wormkit and have both the rubberworm and px dlls in the directory. :)

I do, maybe it's a bug. I took out the PX .dll and /arrows works fine now.

No. This is a bug of load-sequence. If you have Windows XP, then it is a known problem - Windows XP tends to load .dll modules by their alphabet (or other) sorting, as they are. So wkPX.dll loads before wkRubberWorm31.dll and overrides its /arrows feature. As we got now, it turns out that this can be fixed from RubberWorm's side, but I don't know when will Kawoosh release the next version.
So, just rename wkRubberWorm31.dll to something in alphabet before "wkPX", like "wkPubberWorm" etc.

Or rename project X to wkZx.dll :P

I have Windows 7 Ultimate. :P

No way, PX checks its name.

Then you are trapped, bad luck, because the algorythm of load sequence on Vista & 7 is unknown for me. Perhaps it's something I don't know, but /arrows work here. You can either try messing with your modules to see if you've got the desired result. Also, if you are using WormKit, try WormKitDS, but I'm not sure that this will help.
The last solution is to either delete PX or wait for the new RubberWorm version.
