PEAR - My hosting company killed it

Hi, I know this is the probably the wrong list for this question, but I'm a bit desperate as my hosting company has disabled PEAR on the server, and I was using it extensively on more than one website... suddenly my weekend looks like a coding nightmare. The hosting service reports a security issue, but no details. Has anyone using PEAR here run into this problem? Is there any potential resolution beyond recoding everything? I'm looking at better than ten sites to recode at this point, so other options would be greatly appreciated. The hosting company didn't give me any warning that this was going to happen. Thanks, Dianne
