Hi,

for some reason, this evening when i open the LGP file i've been working with for the last 7 months, LLBL gives the following exception : Possible Version mismatch. Type System.Collections.Comparer has 1 members, number of members deserialized is 0. stack trace :

I try getting an earlier version of the LGP from sourcesafe, and it gives me the same error. I copied my whoe prgram files/llblgen directory to another pc and tried it there, works fine

how could this be ? i haven't installed any new stuff lately that i know of ... holding off VS2005 until this project is finished for exactly this kind of reason

using LLBLGen build 1.0.2004.2 Final 26/may/2005 RuntimeLibraries_10082005.zip Templates_10122005.zip

any idea ??

Update:

i copied my whole program files/llblgen directory to another pc (Windows 2003, no Visual studio installed) and there i could open the LGP file

... ??

I believe installing .NET 1.1 Service Pack 1 will resolve the problem:

Yes, SP1 for .NET 1.1 will fix this. Install it on the computer on which you get this error.
