Issues with Media Gallery?

Hi,

I'm using Media Gallery, plus the latest version of Webform Multiple File Upload and when an image is downloaded from the Gallery, I get the following errors...

Notice: unserialize(): Error at offset 0 of 11 bytes in webform_multifile_file_download() (line 78 of ..../sites/all/modules/contrib/webform_multifile/webform_multifile.module).

and

Warning: in_array() expects parameter 2 to be array, boolean given in webform_multifile_file_download() (line 79 of ..../sites/all/modules/contrib/webform_multifile/webform_multifile.module).

Also, this pair of errors does not happen just once, but more like 2-3 DOZEN times...
