This is supposed to be Adobe Flash player error, please refer to this KB doc. for help Flash Builder - Flash Player throws Error #2148 because it doesn't re-read trust files (.cfg).
Many thanks for your reply to my plea for help, however, when I try to open the link below I get the following message on a black screen, "Error loading player. Could not load player configuration." The other e-mail you sent had another reference that indicated I should debug my computer but again I was unable to decipher the instructions for that. Since I am not experienced at interpreting and/or fixing problems with computers I am at a loss as how to proceed. Do you have any other instructions that could perhaps be interpreted by a non-computer savy person?? I desperately need some help. Thanks, Pat
