USB Loader GX Not installing games

New users, so not sure if this is the right area to post.
Anyway awhile ago I put USB Loader GX on my Wii and at the time I copied all the games I had over to my flash drives (2 32gig Sans Disk) at the time. Ive now gotten a few more Wii games that id like to make Back ups of but when i try to install the games to my Flashdrive or External HDD the install stops at about 2 or 3 percent.
Is there any fix for this, or any work around?
Thanks in advance for any advice

There are several things you could try:
If you did not mod your wii using our softmod any wii guide, remod it using the guide. Should solve most issues.
If you did mod using our guide, you could try another USB loader.
If that doesn't work, you could try using cleanrip, but you'll need to convert the iso it creates using wii game manager.
