Ok..after getting tired of rebuilding paths to include /interface/addons when most mods dont use this, I made a change to extract to this directory automatically. So if you want to use this replacement file, your zip package should just be a single folder (/modname, in most cases).

Also, I found that uniuploader was failing for some mods (most notably ctraidassist). Turns out any mod/directory that has a read-only file causes the update to fail. To correct this, I wrote a new routine which strips the read-only tag off all the files and folders in the old mod directory.

As a reminder, if you have a zip file with /interface/addons/mod as the structure, you'll have to make a new zip with just /mod. However, this is much easier as you can zip up your own /interface/addons/mod directories in a batch with winrar and specify 'new archive for each folder', making the process MUCH easier.

1) get the uniuploader source and extract it
2) overwrite the Forms1.cs file with the one attached here
3) rebuild the project

C# Express is now a freebie, so $ is no excuse

Hope this helps someone other than me.
