Assuming Sleeprider's info is correct you can ignore the rest of this message.
Posting for future reference to completely uninstall Sleepyhead.
I know you tried uninstalling the program. After you did, did you also delete the data folder? It doesn't get deleted since it changes after you install the program. The default folder is located in documents.
If you go to
Help >
About Sleepyhead on the SH menu, it will list the location of the data folder.
What I would try next is uninstall SH, go into the document folder and delete the SleepyHead_Data folder, then open RegEdit by going to start > run and type in
regedit. Navigate to HKEY_CURRENT_USER and expand that. Scroll down to SOFTWARE and expand that, scroll down until you see Jedimark. Right click on Jedimark and choose delete.
Then just for giggles, go to Start > Run and copy/paste this:
%appdata%\..\Local\VirtualStore
If you see any folders for Program Files or Program Files (x86) click into each one and see if there are any additional SleeyHead folders. If there are, please delete those.
Reboot your computer for another laugh (I know I'm not laughing either). This will give you a completely clean slate sleepyHead-wise and you can once again reinstall SleepyHead. Set up your profile again, reimport your data and crossing fingers and sacrificing Bob the lamb to Bill Gates, Sleeyhead should work as intended. You still may need to use the BrokenGL version though.
