PSP 8, even after the 8.10 update, still doesn't save TGA's properly. Jasc is aware of this, coz I've sent them the details with screenshots.
But there is a solution to the problem......... save as PNG, and import it into SkinStudio. SS will convert the PNG to TGA. Works perfectly. 
ps.... In PSP 8.10 (I don't think this option is in 8, or 8.01) go to FIle > Preferences > File Format Preferences > PNG tab > "Load and save transparency from / to alpha channel"....
this setting may or may not have any effect on SkinStudio, but I know for a fact it will really give HoverDesk a fit if PNG's are saved with this enabled. ......... just be aware of this setting, if your import goes south.
