The first thing I would try is something like Norton Disk Doctor to see if it can "recover" the files without mounting the drive.
Probably the last thing I would try is an "Install New Driver" or "Update Driver" from one of the other disk driver packages mentioned previously. If you can take over management of the disk from Silverlining, and assuming that Silverlining just locked access/mounting, but did not encrypt the contents, then it might be possible to do a friendly takeover.
I'd be careful of "format" as anything that does a real format will erase the contents. But "format" is often used when what they really mean is that we're going to replace the driver resident on the disk and maybe erase the file directory.
In the latter case, you'll still need to use a file recovery tool.
