HELP!!!

Okay iv been making mods for about 3 years now and have never had any problems with the geck or using gimp 2.0 before. But now i have just decided to start releasing my mods, they are simple re-texture mods on the vanilla weapons. But my problem is that i have the gimp 2.0 dds plug in to avoid having to go through the process of converting files from dds to jpeg and then back to dds. I have been working for 2 days on this re-texture and was excited to release it however the geck wont open the file. I have saved it in nifskope and placed the re-texture on the gun and it works just fine, in fact i have even saved the nif file and everything seemed fine. My problem is that now with the dds plug in for gimp im pretty sure all of my dds files are invalid directories. I made sure the mipmaps were selected off and re sized it and all that, like i said iv been doing this for three years. Iv managed to have other mods work perfectly fine using this same method before, except iv never really used the dds plug in for gimp (yes i saved it correctly). Iv saved the retextures to my data folder several times and iv even tried formatting which programs open them so only the geck can and it still comes up with the error message invalid directory. I have never had this problem before when trying to add new textures iv even tried going all the way back and using the old dds converter to try and redo the process to see if it would work then, but it wont. Iv tried dragging it to my desktop and formatting the programs it opens with, the size, the mipmaps, and even converting it from dds to jpeg and back and then putting it back into my data folder. I am so stuck i have no idea whats going on i dont know how to fix my problem or if I am ever going to be able to make mods ever again. The geck will not even read all of the old texture files that i exported from FOMM. They all come up as gimp dds files now no matter where i place them or convert them...

Please help me modding is what keeps me sane.
