Still sounds like your itemcol.db in your C:\Program Files\EQ Item Collector\ directory is corrupted, since it appears to be working for other people. It's rare for this error to be anything other than the program itself, or that file corrupted. After doing the following, and you still don't see any profiles, then I'd delete the itemcol.db file. It contains all the items and toon profile information, and is probably corrupted.
As far as setting up Profiles, do the following:
Options - Settings
In that window, check Profile Support check box, and use the ... button to browse to a folder (My Documents, is probably a good one.
Click the Ok button.
Run EQ, and log in a toon. Then check EQ Item Collector by doing:
Files - Profiles
In that window see if any toons appear. If they do, select the one you want an HTML file for, and press the Export button. You will now have a file of the form Character-###.html in whatever directory you selected for Profile Support above. Character = the name of the character, and ### = a number for that sever.
