Im not sure but i think it has to work with thawspace. I have never workd with thawspace but i know how it works. A extern HD wont work because you need to install de drivers and USB services has to be running. And you dont got the premission for that. So what you need to do is:
Take your folder from you own pc, (c:\program files\silkroad\) copy it, make it a RAR or something. Put it on the internt (rapidshare enc) put it on your thawspace (T: ) and run it. Its the only solution.
ps: What you can do is go to your administrator for rights to right on the C:\. ^^ That would be the perfect solution. Else go and work
