[Plugin: ProjectManager] Multisite error with images and subdirectories

Im using network multisite with subdirectories and not subdomains.

When adding a dataset on a subsite with a fieldtype of image, I get the following error:

Warning: move_uploaded_file(/home/ccblues/public_html/wp-content/uploads/projects/137_2010_M_Aldas.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/ccblues/public_html/wp-content/plugins/projectmanager/admin/admin.php on line 1026

So after submitting the dataset, everything but the image appears to have been added/updated.

Any suggestions?
