I had basically the same problem and errors; I deleted the user files (for me they were in C:\WINDOWS\phex) such as phex.cfg (making a backup of that one so I could copy the info back into Phex) and when I reloaded Phex it worked again. There was a similar problem previously; iiRC, it has to do with the spacing of the columns (i.e. remote host, vendor, etc. if they are too wide, it creates an error and Phex crashes)
